A straight wire 0.10 m long carrying a current of 2.0 A is at right angles to a magnetic field. The force on the wire is 0.04 N. What is the strength of the magnetic field?

The strength of magnetic field is 0.2 Tesla.

Explanation:

Data from the question is

Length (L) of wire ; L=0.10 m

Current in wire ; I= 2.0 A

Force on wire ; F = 0.04 N

Angle = Right angle So,

Now ,

We have to find the magnetic Field strength (B)

For this formula for Force on wire in magnetic field is

Further modified as

Now insert values in the formula

So, the strength of magnetic field is 0.2 Tesla.
