# $$\epsilon$$ Day Problem 1

Electricity and Magnetism Level pending

Krish just learnt about the works of Michael Faraday and got amazed to learn them.

He tried to do an experiment for the same at his home. He took a coil with 12 loops and surface area of 20 $${m}^{2}$$. He also noticed that the magnetic field strength is in the form [$${t}^{2}$$ + 56789], where t is the time the magnet was inside the coil. He wonders for what minimum time he has to keep it inside the coil so that $$\epsilon$$ is maximum?

Note: Krish has now generated a love for the 1000th decimal place but surely not beyond it!
