Question

Two coils are placed, such that their planes are at right angles to each other and have common center. If each coil carries the same current and produces same magnetic field b , then the resultant field will be:

Answer 1

★ Suppose magnetic field by coil 1 = B1

and magnetic field by 2nd coil ,= B2

★ Now,

B1 = B2 = (Mu.nod.I)/2r

Net magnetic field B' = B1 + B2 ( vector sum)

B' = √2B

= √2(mu.nod.I)/2r

= mu.nod.I/√2r

happy to help!
