Question

A 2 m long wire carrying 2 A of current pointing to the right is placed in a magnetic field of 4 T directed away from you.

How big is the force acting on the wire?
A. 4 N
B. 8 N
C. 12 N
D. 16 N

Answer 1

Given: i=10A,B=0.15 T,θ=45

∘

and l=2 m

Force on a current carrying wire of finite length =

F

=l(

i

×

B

)

Hence, magnitude of force, F=Bilsinθ

=0.15×10×2×sin45

∘

=

2

3

N

Answer 2

Answer:16

Step-by-step explanation:

as F=BIL so by placing value's B is magnetic field 4 and i is current 2A and l is length that js 2 m so answer is
