Question

A wire 10cm long and carrying a current of 1.5 A is held in a uniform magnetic field of 10^-3 T. Calculate force on the wire if it held perpendicular to lines of magnetic field.

Answer 1

A wire 10cm long and carrying a current of 1.5 A is held in a uniform magnetic field of 10^-3 T. Calculate force on the wire if it held perpendicular to lines of magnetic field.

Good question,

Here is your perfect answer!

Length of wire = 10cm

= 10/100 = 0.1m

I = 1.5A,

B = 0.001T

Force = BIl

(Magnetic field * current * length of wire)

=) F = 0.001 * 1.5 * 0.1

= 15* 10^-5 N.

Answer 2

F = biL

= 0.001 * 1.5 * 10/100

= 15 * 10^-5 N.
