This is the idea behind power generators: • Spin a magnet with a mechanical source (e.g. water) • The changing Magnetic field induces an AC current in nearby wires • The current can then be sent to an "outlet" (or applied directly as shown here)pic.twitter.com/u6KuTAouvi

This is precisely how "induction stoves" work • The oscillating magnetic field wirelessly induces a current in the pot • The current flowing through the pot results in resistive heating The coolest thing about induction stoves is that the stovetop itself doesn't get hot!pic.twitter.com/sLC3hDyAun

Is there a maths, shape or formula given to magnetic fields?

It's absolutely crazy to think the majority of the world's power infrastructure (with the notable exception of PV cells) is based entirely on evaporating water into steam to turn a magnet. That honestly blew my mind when I learned even Nuclear reactors function in this way

I think it is similar to Faraday Dynamo,Am I right sir...
