Two similar coils of radius R are lying concentricaly with their planes at right angles to each other. The current flowing In them are l and 2l, respectively. The resultant magnetic field induction at the centre will be?
Magnetic field at the centre of circular current carrying coil of radius R and currect I is= μ0I/2R=B
Magnetic field at the centre of circular current carrying coil of radius R and current 2I is = μ02I/2R=2B
The resulting magnetic field will be =√ [B^2+(2B)^2]=√5 B
