how are electricity and magnetism related?

Answer 1

Any moving electric charge creates a magnetic field.

Thus, if you have a wire with no current flowing through it, there is no overall field (though electrons moving around atoms still make tiny tiny ones). But once electrons start moving through it, you get a field around the wire. That's essentially what electromagnets take advantage of.

This works in reverse, too. A magnetic field can exert a force on electrically charged particles moving through it. Stationary particles are unaffected. This is essentially how the Earth's magnetic field protects us from cosmic rays.

Answer 2

Primarlly because both involve movement of electrons (those tiny little negatively charged particles that spin like little planets around the core of atoms).
Simply put electricity is the movement of electrons thru a metal (copper) wire.
Whenever electrons move thru a wire, they creat a magnetic field (around the wire).
Conversely, whenever a wire moves thru a magnetic field it cause electrons to move along the wire.
In a electric motor equipped with an rotor of many individual iron magnets around its circumference, running electricity thru the coils of wiring surrounding the rotor pulls the little magnets to cause the rotor to turn a little bit. Then the electric is reversed to push the little magnets a little more. The electric is reversed again & again, faster & faster until the motor is spinning away - turning a fan or pumping water or whatever.
Not too amazingly, the electric current that turns the motor is created by the reverse process. A rotor is turned (by water from dam or steam engines run by coal) and the rotor's magnetic field causes electrons to move in wiring nearby. An electric motor in reverse!
Permanent magnetics, by the way, result in materials (iron, for instance) which have single electrons at their outer "shell". Each electron has a magnetic field. When iron is heated or hammered, the individual atoms are shaken up and they re-align so that all their magnetic fields point in the same direction (since north poles want to stay away from south). Once aligned, some materials such a iron will stay permanently aligned. Some iron is discovered already magnetic from being exposed to volcano heat and the earth's magnetic field.

Answer 3

Through the Maxwell equations.
A moving electrical charge makes a magnetic field.

Answer 4

Magnets exert forces on one yet another. they are equivalent to electric powered expenditures, for they might the two attraction to and repel devoid of touching, finding on which end is held close to the different. only as an electric powered charge is surrounded by ability of an electric powered container, an identical charge is likewise surrounded by ability of a magnetic container no count if that's moving.

Answer 5

As the sun radiates electro-magnetic waves they propagate(travel) according to the Right Hand Rule. Extend your fore finger and leave the other three fingers ninety degrees to the left. Now point your thumb ninety degrees away from your fore finger and ninety degrees away from the other fingers. The electro part moves in the direction of your fore finger and the magneto part moves in the direction of the other fingers. Whe wave progagates in the direction of your thumb. They are related orthoganally (in right angles to each other).
