• What is the magnetic field?

$\huge\underline\mathfrak\black{Answer:-}$

Magnetic Field:-

The magnetic field is the area around amagnet in which there is magnetic force. Moving electric charges can make magnetic fields. 

Units Of Magnetic Field:-

A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss). The magnetic quantity B which is being called "magnetic field" here is sometimes called "magnetic flux density.

Uses Of Magnetic Fields:-

Magnets are responsible for making electric motors and generators work. Moving a metal wire near a magnet produces electricity. Electric generators use steam, flowing water or another source of energy to spin wires through a magnetic field and create electricity.

Formula Of Magnetic Field:-

A current-carrying wire feels a force in the presence of an external magnetic field. It is found to be F=Bilsinθ F = Bi l sin θ , where ℓ is the length of the wire, i is the current, and θ is the angle between the current direction and the magnetic field.
