Unit 20 Magnetic fields

Magnetic field

A region of space where a magnetic pole experiences a force

Magnetic field lines

are the lines in a magnetic field, the tangent of which at any point will give the field direction at that point. They start at the north pole and end at the south pole

Electromagnetic effect

Electric current produces a magnetic field when passing through a wire or solenoid

Ampere’s Force Law

Fleming’s left-hand rule (motors)

The pointer finger is showing the magnetic field lines from north to south. the middle finger shows the current from positive to negative and thumb shows the direction of the force

Fleming’s right-hand rule (generators)

Fleming's right-hand rule: thumb for motion, forefinger for magnetic field, middle finger for current direction.

Magnetic flux density B

the force per unit current per unit length, measured as Tesla

Nuclear Fusion vs Nuclear Fission

• Nuclear Fusion: Combines light atomic nuclei to form a heavier nucleus, releasing vast energy.

• Nuclear Fission: Splits heavy atomic nuclei into lighter fragments, also releasing energy.
