A0.676 m long section of cable carrying current to a car starter motor makes an angle of 57.7º with the earth’s 5.29 x 10^−5t field. what is the current when the wire experiences a force of 6.53 x 10^−3 n?

The current in the wire under the influence of the force is 216.033 A

Solution:

According to the question:

Length of the wire, l = 0.676 m

Magnetic field of the Earth,

Forces experienced by the wire,

Also, we know that the force in a magnetic field is given by:

I = 216.033 A

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
