How a magnetic field is produced by moving charges. How can a magnetic field be produced around a wire? Why does electricity create a magnetic field? How to produce a uniform magnetic field. How are electrons responsible for magnetism?
How to create a magnetic field. How to calculate the magnitude of a magnetic field? How strong is Earth's magnetic field? What determines the strength of a magnetic field? How does Earth's magnetic field resemble a bar magnet? How to produce a uniform magnetic field. ...
but the whole family can’t stop playing with them. And the science behind them is pretty cool too. Magnetic ink floating in water allows you to see the elusive magnetic field of a magnet.

Whenever electricity flows through a wire, it creates a magnetic field. In a single wire, this field is usually pretty weak. A coil, however concentrates the magnetic field. Each coil of wire contributes a small magnetic field and, together, they add up to make a much more powerful magnet...
All magnetic fields are created by moving charged particles. Stationary charged particles do not generate magnetic fields. An electromagnet is a magnet that relies on an electric current to produce the magnetic field. The simplest electromagnet is simply a wire carrying a current, which generates a...
But it is generally accepted that these ferromagnetic elements have large magnetic moments due to un-paired electrons in their outer orbitals. This is like having current flowing in a coil of wire, creating a magnetic field. Even the spin of the electron is thought to create a minute magnetic...
5. Turn the jar in place. Does the needle continue to point north? The metallic core of the earth helps create the earth’s magnetic field with north and south poles. The compass reacts with the earth’s poles to point in the direction of the earth’s North Pole. ...
