A 0.15 m length of current carrying wire is placed?
A 0.15 m length of current carrying wire is placed at right angles in a magnetic field of 0.015-T. Calculate the current in the wire when it experiences a force of 0.030-N.

You can use
Force= I H, I is the current and H
is the magnetic field. This gives
I = F/H= 0.03/0.015= 2 A
