A 1.0-m long wire is carrying a certain amount of current. The wire is placed perpendicular to a magnetic field of strength 0.20 T. If the wire experiences a force of 0.60 N, what is the magnitude of the current moving through the wire?
A) 2.0 A
B) 1.0 A
C) 3.0 A
D) 4.0 A
E) 5.0 A

The equation for calculating the force on a current-carrying wire in a magnetic field is given by F = BIL, where F is the force, B is the magnetic field strength, I is the current, and L is the length of the wire.

Rearranging the equation to solve for the current, we have: 
I = F/(BL)

Plugging in the given values, we get: 
I = 0.60 N / (0.20 T x 1.0 m) 
I = 3.0 A

Therefore, the magnitude of the current moving through the wire is 3.0 A. Option C is the correct answer.
