The Biot-Savart Law can be used to calculate the magnetic field near a straight wire that can carry a limited amount of current. The following mathematical expression can be used to describe the magnetic field near a straight wire that carries current:
The area around a magnet where magnetism has an effect is called the magnetic field. We describe the distribution of the magnetic force within and around a magnetic object by utilizing the magnetic field as a tool.
The equation describing the maximum EMF induced in a rotating planar coil (M = 75.0 V, N = 260turns, angular speed = 89 rad/s, magnetic field B = 0.3T) can be connected to the coil's area, which is A=a2 because it is a square of the side length.
The side length can be derived from this:
√∈M/NBω
