Question

A 0.6 m length of current carrying wire is placed in a uniform magnetic field oriented perpendicularly to the wire. The current is 4 A and the magnitude of the magnetic field is 10 T. What is the force on the wire?

a. 0 N.
b. 2.4 N.
c. 6 N.
d. 24 N.
e. 30 N.

Answer 1

D. The force on the wire is 24 N.

Step-by-step explanation:

Given;

length of the wire, L = 0.6 m

current in the wire, I = 4 A

magnitude of the magnetic field, B = 10 T

The fore on the wire is calculated as;

F = BILsinθ

where;

θ is the angle of inclination of the wire on magnetic field = 90°

F = (10)(4)(0.6)(sin 90°)

F = 24 N

Therefore, the force on the wire is 24 N.
