What is the direction of the magnetic lines in a magnet?
The lines of magnetic field from a bar magnet form closed lines. By convention the field direction is taken to be outward from the North pole and in to the South pole of the magnet. See also how did the transcontinental railroad help unite the nation
How do you find magnetic force?
The magnetic force on a charged particle q moving in a magnetic field B with a velocity v (at angle θ to B) is F=qvBsin(θ) F = qvBsin ( θ ) .
Can a constant magnetic field set a proton at rest into motion?
No. The force that a constant magnetic field exerts on a charged particle is dependent on the velocity of that particle. If the particle has zero velocity it will experience no magnetic force and cannot be set in motion by a constant magnetic field.
What causes the magnetic lines of force in a magnet?
All magnets have north and south poles. Opposite poles are attracted to each other while the same poles repel each other. When you rub a piece of iron along a magnet the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

What is the direction of the magnetic force on wire 2?
We have obtained the relation for the magnitude of the magnetic force F2 by which the second wire affects the first one. Direction of the magnetic force can be determined by the Fleming’s left-hand rule. In our case magnetic force →F2 is directed to the right.
What is magnetic field direction?
• The direction the magnetic field produced by a. moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.
What is direction of force Class 8?
All pushes and pulls are forces and the direction in which an object is pushed or pulled is considered the direction of the force.
How do you find direction of force?
To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right and a force of 3 N act to the left. Calculate the resultant force.
How do you determine the direction of force on a current carrying wire in a magnetic field?
How do you find the direction of force on a current carrying conductor?
What is the direction of the magnetic force on the wire?
The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.
What is the direction of the magnetic force on the current Chegg?
The direction of the magnetic force can be determined by the right hand rule-1. According to this rule for a positive moving charge right thumb is in the direction of current fingers point in the direction of magnetic field and perpendicular to the palm points is the direction of magnetic force.
Where is the North Pole right now?
Based on the current WMM model the 2020 location of the north magnetic pole is 86.50°N and 164.04°E and the south magnetic pole is 64.07°S and 135.88°E.
What is the direction of magnetic moment?
The direction of the magnetic moment points from the south to north pole of the magnet (inside the magnet). The magnetic field of a magnetic dipole is proportional to its magnetic dipole moment.
What is the direction of the magnetic force on the current in each of the six cases in the figure below?
So you might say north or up is the direction of the force here. And in part d because the current and the magnetic field lines are parallel there is no force in this picture. There’s only a force if there’s a component of the current that is perpendicular to the magnetic field lines and in this case there is none.
What Is The Direction Of The Magnetic Force On This Wire Due To The Magnet??
The direction of magnetic force on the wire due to magnet is determined by using the Fleming’s left-hand rule. When a current carrying wire is placed in a magnetic field the conducting wire experiences a magnetic force perpendicular both to the magnetic field and to the direction of current flow.
What is magnetic line of force?
Magnetic Lines of Force is a an imaginary line representing the direction of magnetic field such that the tangent at any point is the direction of the field vector at that point.
How do you find the direction of magnetic moment using the right hand rule?
The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge point your right thumb in the direction of the velocity (v) your index finger in the direction of the magnetic field (B) and your middle finger will point in the direction of the the resulting magnetic force …
What is north and south pole in magnet?
magnetic pole region at each end of a magnet where the external magnetic field is strongest. … The north-seeking pole of such a magnet or any similar pole is called a north magnetic pole. The south-seeking pole or any pole similar to it is called a south magnetic pole. See also how are abiotic and biotic factors related
What is magnetic force on a current-carrying conductor?
The magnetic force on current-carrying conductors is given by. F=IlBsinθ F = I l B sin where I is the current l is the length of a straight conductor in a uniform magnetic field B and θ is the angle between I and B. The force follows RHR-1 with the thumb in the direction of I.
What is the direction of force?
The direction of the force is in the direction opposite the object’s direction of motion. When the interaction ceases the two objects no longer experience the force. The direction of the force is perpendicular to the direction the object moves. Forces only exist as a result of an interaction.
Where is the magnetic force of a magnet the strongest?
poleThe magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole. See also the modern age was born in what american city
Where is magnetic pole?
What is the Magnetic North Pole? The Earth is one big magnet. The Magnetic North Pole (also known as the North Dip Pole) is a point on Ellesmere Island in Northern Canada where the northern lines of attraction enter the Earth.
What is the direction of magnetic field outside a bar magnet?
North pole to south pole is the direction of magnetic field lines outside a bar-magnet.
Magnetic force on a current carrying wire | Physics | Khan Academy
What is the direction of the magnetic force on a negative charge that moves as shown?
The force on a negative charge is in exactly the opposite direction to that on a positive charge. Figure 1. Magnetic fields exert forces on moving charges.
What is the direction of force between two parallel wires carrying current in opposite direction?
What is the nature of force between two parallel wires carrying current in opposite directions? Solution : Two parallel wires carrying current in opposite directions repel and try to move away from each other.
How do you know the direction of current in a wire?
Using the right hand rule for the conventional current in the wire the right thumb is pointed along the wire pointing to the left. At point the fingers curl around and point up out of the screen. This can be verified by putting the thumb in the direction of current anywhere in the circuit.
What is the direction of magnetic lines of force produced by passing a direct current in a conductor?
The lines of the magnetic field will be perpendicular to the flow of current on one side according to the “right hand rule” convention. The length of the region near the surface of the conductor will be the strongest and will decrease as the distance from the conductor increases.
What is the force between two current carrying wires what direction is this force?
The direction is obtained from the right hand rule. Note that two wires carrying current in the same direction attract each other and they repel if the currents are opposite in direction.

What is the direction of force you applied?
An applied force is an interaction of one object on another that causes the second object to accelerate or change velocity or direction. The force can be a push pull or drag. The resulting direction of an object depends on the relative direction of the force on the object. A force equation is F = ma.
