Two identical coils carry equal currents have a common centre and their planes are at right angles to each other. The ratio of the magnitude of the resulatant magnetic field at the centre and the field due to one coil is

Two identical coils have a common centre and their planes are at right angles to each other. They carry equal currents. If the magnitude of the magnetic field at the centre due to one of the coils is B then that due to the combination is

Two identical coils carrying same current have common centre but have their planes at right angles to each other. If the field due to each is B, what is the resultant field?

The magnetic field at the centre of the current carrying coil

The magnetic field at the centre of current carrying coil is

Two similar circular loops of radius R are lying concentrically with their planes at right angles to each other. The currents flowign in them are l and lsqrt(3) respectively. The magnetic field at the centre of the coil is

Why is magnetic field maximum at the centre of a current-carrying coil?

Two similar coils each of radius r and no. of turns n are lying concentrically with their planes at right angle to each other. The corrents folowing in them are 1 A and sqrt3A respectively. What is the magnetic field at centre of the coils ?
