7.1 - Permanent and Induced Magnetism, Magnetic Forces and Fields

At which part of a magnet of a magnetic forces strongest?

The poles of the magnet

What happens when two magnets are brought close to each other?

The exerted force on each other

What type of force is exerted if two lightpoles of a magnet are brought in near each other?

A repulsive, no noncontact force

What type of force is exertive to unlike poles of a magnet are brought near each other?

An attractive noncontact force

What is the difference between a permanent magnet and an induced magnet?

A permanent magnet produces its own magnetic field

An induced magnet becomes a magnetic when placed in a magnetic field

What type of force does induced magnetism always cause?

A force of attraction

What happens when an induced magnet is removed from a magnetic field?

The induced magnet loses most / all of its magnetism

What is a magnetic field?

The region surrounding a magnet where another magnet or magnetic material experience is a noncontact force

Give four examples of magnetic materials

Iron

Steel

Cobalt

Nickel

What can be said about the force between a magnet and its magnetic material?

It's always attractive

How does the strength of a magnetic field alter as you move further away from the magnet producing it?

The magnetic field strength decreases the further you move away

In what direction does a magnetic field point?

In the direction that North Pole would experience a force if placed in the field

From the north seeking port to the south seeking pole of the magnet

What does a magnetic compass contain?

A small bar magnet that points in the direction of earths magnetic field
