Question

A straight wire of length 0.75 m carries a current of 35 A. The wire is at right angles to a magnetic field of strength 0.058 T. Calculate the force on the wire.

Answer 1

Answer

Given data as below

Length of wire L=0.75m

Current in wire I=35A

magnetic field of strength B=0.058 T

Right angle $\theta=90°$

Force on this wire given by

$F=ILB \sin\theta$

Putting all values

$F=35\times0.75\times0.058\times\sin90°$

$F=26.25\times0.058\times1\\F=1.5225N$

So force on this wire is 1.5225N.
