Explain different ways to induce the current in a coil.
Induced current:
Mathematically, flux can be represented as:
Magnetic flux,
Here,
is the field.
is the area of the loop.
is the angle between the field and the area vector.
According to Faraday's First, induced emf,
According to Ohm's law, induced current,
, where I is the current. and R is the resistance,
Different ways of creating induced current in a coil:
