A wire 2.80 m in length carries a current of 4.20 A in a region where a uniform magnetic field has a magnitude of 0.260 T. Calculate the magnitude of the magnetic force on the wire assuming the following angles between the magnetic field and the current.

.

F = 3.0576sinθ

For any value of θ < 180

Explanation:

Generally, F = BILsinθ

Where,. F = magnetic force magnitude. B = magnetic Field magnitude.

L = length of wire. I = current

Therefore,

B = 0.260 T, L = 2.80 m

I = 4.20 A

: F = 0.260 × 4.20 × 2.80sinθ

∴ F = 3.0576sinθ

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
