ADDITIONAL INFORMATION

➛ Magnetic field are like concentric circles.

➛ Magnetic field inside the magnet goes from South pole to north pole.

➛ Magnetic field outside the magnet goes from north pole to south pole.

➛ Magnetic force is greatest at the pole and lowest at the sides.

Answer 2

Answer:

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field

Explanation:

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.

The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law F magnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).

A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).The formula for the energy stored in a magnetic field is E = 1/2 LI2. The energy stored in a magnetic field is equal to the work needed to produce a current through the inductor.
