Magnetic Field Patterns.

Every magnet or magnetic object has a magnetic field – the space around the magnet in which its magnetic force is present. It is the space affected by the magnet’s magnetic charge.

Permanent magnets and electromagnets have enduring magnetic fields, which you will conventionally see with iron filings that arrange themselves into the shape of the magnetic field lines. These will follow the flow from the magnet’s north pole to its south pole. Magnetic fields change depending on the strength of the magnet.

Plotting field patterns

A line of force gives the direction of the magnetic field at each point along it.

Their closeness is a measure of the strength of the magnetic field or of the force that would be exerted by the bar magnet.

Examples of field patterns.

The points marked ‘X’ are called neutral points where there is no magnetic field at such points.

Watches (non-digital), electron beams in cathode ray tubes and TV sets are shielded from external magnetic fields by placing a soft-iron cylinder around the neck of the tube or watch.
