What Is The Formula Of Magnetic Field At The Centre Of The Coil?
What Is The Formula Of Magnetic Field At The Centre Of The Coil? Since the direction of all four magnetic fields is same, the magnetic field produced by one such coil at the centre is equal to 4B=4(μ0i2√2πl)=√2μ0iπl. It is given that there are n turns in the coil. Therefore, the net magnetic field at
