What is the magnetic force on the charge?

The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule. The force is given by the charge times the vector product of velocity and magnetic field.

What is the magnetic force law?

Magnetic Force The force is perpendicular to both the velocity v of the charge q and the magnetic field B. 2. The magnitude of the force is F = qvB sinθ where θ is the angle < 180 degrees between the velocity and the magnetic field.

What is Ampere’s law for magnetism?

Ampere’s Law states that currents generate magnetic fields or in other words, whenever you have a current, there is a magnetic field circulate around it. Ampere’s Law is expressed in the equation magnetic field x 2(pi) x radius = constant x current(passing through that path).

What is the relationship between magnetic force and current?

Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is doubled the force on the conductor will double.

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 ) .

What is ampere current law?

Ampere’s Law is one of the important law of Electromagnetism. It is finding the expression for any closed-loop path. It states that the sum of the length elements times the magnetic field in the direction of the length element will be equal to the permeability times the electric current.

Which of the below is amperes law?

Explanation: Ampere law states that the line integral of H about any closed path is exactly equal to the direct current enclosed by that path. ∫ H. dl = I The point form will be Curl (H) = J. 2.

What is the relationship between the magnetic force and the length of a conductor with current in the magnetic field?

For a wire exposed to a magnetic field,F=IlBsinθ F = IlB sin ⁡ describes the relationship between magnetic force (F), current (I), length of wire (l), magnetic field (B), and angle between field and wire (θ). The direction of the magnetic force can be determined using the right hand rule, as in fig [[17951]].

What is the magnetic force on the electron?

The magnitude of the electric force acting on the electron is equal to Fel = keqe2/r2. The maximum magnitude of the magnetic force acting on the electron when its velocity v is perpendicular to B is Fmag = qevB. Details of the calculation: Fel = keqe2/r2 = 9*109*(1.6*10-19)2/(0.53*10-10)2 N = 8.2*10-8 N.

Why does a magnet apply a force to an electric current?

Because charges ordinarily cannot escape a conductor, the magnetic force on charges moving in a conductor is transmitted to the conductor itself. The magnetic field exerts a force on a current-carrying wire in a direction given by the right hand rule 1 (the same direction as that on the individual moving charges).
