Question

Compute the magnitude of the magnetic field of a long, straight wire carrying a current of 1A
at distance of 1m from it. Compare it with Earth's magnetic field.​

Answer 1

Answer:

The magnetic field will be 4 × 10-7 T

Explanation:

When current passes through a straight wire a magnetic field is produced around that wire. Now, we are going to calculate that magnetic field at 1m away from a wire carrying current of 2A.

We know that:

B = μ0 I/2πr

By putting values in above equation, we get,

B = 4 × 10-7 T
