Magnetic and Electric fields

 describes the trajectory of charged particles which enter, at right angles in a uniform electric field

Parabolic

describes the trajectory of charged particles which enter, at right angles in a uniform magnetic field

Circular

magnetic flux density

the magnetic field strength/ the number of magnetic field lines in a magnetic field per unit area

Magnetic flux

The magnetic field lines in a magnetic field

Magnetic magnetic flux linkage

The amount of magnetic flux interacting with a coil of wire

What happens when you move a coil of wire (connected to a circuit) closer to the magnet?

More field lines interact with the coil and the potential difference across the wire increases.

What is the SI unit of Magnetic flux?

weber (Wb)

What is the symbol for magnetic flux?

its symbol is the Greek letter Phi Φ

What is the SI unit for magnetic flux density?

T (Tesla)

What is the symbol for Magnetic flux density?

B

What is the SI unit for magnetic flux linkage?

weber-turn (Wb turns)

What is the symbol for magnetic flux linkage

ΦN -

Φ= Weber turns

N= the number of coils of wire

What is the equation for magnetic flux density?

What is the equation for magnetic force

1. What are 3 factors that affect the magnetic force due to the motor effect?

1. Strength of the current

2. Strength of the magnetic field

3. The length of the wire in the magnetic field

What is Fleming left hand rule?

how do you find the direction of the magnetic field in a current carrying wire?

Define the Motor effect?

It’s the phenomenon that a current carrying wire held within a magnetic force will experience a force.
