Magnetism

Magnetic field-

A magnet creates a magnetic field in its vicinity.

Magnetism

It represents the effect a magnet has on its surroundings.

Magnetism

All magnetic fields arise from the motion of electric charge.

Magnetism

Magnetic field lines can be used to represent magnetic fields.

The closer the lines are together, the greater the magnitude of the vector

Magnetism

A magnetic field is represented by the symbol

Magnetism

The direction of a magnetic field

at a given location is the direction in which the north pole of a compass points when it is placed in that location.

Magnetism

A charged particle moving in a magnetic field will experience a force if it has a velocity component perpendicular to the magnetic field.

Magnetism

Magnetism

The Magnetic Force Right Hand Rule (RHR)

Magnetism

Magnetism

Velocity selector.

A device with both magnetic and electric fields present. Only charged particles moving with a certain speed will pass through undeflected.

Magnetism

Magnetism

A charged particle moving with a velocity perpendicular to a uniform magnetic field, will move in a circle.

Magnetism

- Forces on a long straight current carrying wire in a magnetic field.

Magnetism

- Forces on a long straight current carrying wire in a magnetic field.

Magnetism

- A long straight current carrying wire has charges moving inside it.

Magnetism

- If it is placed in a magnetic field, it will experience a force

Magnetism

Magnetism

Magnetism

- Direction of magnetic forces in a current carrying loop in a magnetic field.

Magnetism

Magnetism

Magnetism

- To calculate the magnitude and direction of the magnetic field in the vicinity of a long straight current carrying wire.

Magnetism

- Apply the magnetic field right hand rule.
- Point your thumb in the direction of current flow.
- Curl your fingers around the wire
- They will point in the direction of the magnetic field.
