Question

A 0.4 m wire, stretched horizontally, carries an electric current of 15 A, in a magnetic field whose magnetic field intensity is 0.1 N/Am. What is the magnitude of the wire?

Short Note

Solution

Given: l = 0.4 m, I = 15A
Magnetic induction B = 0.1 N/Am
Solution:
Force to be used F = B I l
= 0.1 × 15 × 0.4
F = 0.6N
