# What happens when you force magnets together?

## What happens when you force magnets together?

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.

## What happens when a charged particle enters a magnetic field?

A charged particle experiences a force when moving through a magnetic field. If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field.

## What is the difference between electric fields and magnetic fields in terms of their impact on a charged particle?

An electric field may do work on a charged particle, while a magnetic field does no work. The Lorentz force is the combination of the electric and magnetic force, which are often considered together for practical applications. Electric field lines are generated on positive charges and terminate on negative ones.

## Why do moving electrons produce magnetic fields?

It requires electrons and protons to produce a magnetic field. As the electrons move relative to protons (ions) there is a relativistic charge per unit volume difference between the positive and the negative charges. This causes any external charges to feel a force we know as the magnetic field.

## Does moving charges produce magnetic fields?

A charged particle moving without acceleration produces an electric as well as a magnetic field. It produces an electric field because it’s a charge particle. All of a sudden when it starts moving, it starts producing a magnetic field.

## How do electrons produce magnetic fields?

Magnetism is caused by the motion of electric charges. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom. Their movement generates an electric current and causes each electron to act like a microscopic magnet.

## What does it mean if jewelry sticks to a magnet?

Did you know you can quickly determine if a piece of metal jewelry is definitely not gold or silver by placing a magnet over it? If the magnet sticks to the piece, move along, it’s not gold or silver.
