All magnets, whether permanent or electromagnetic, are caused by the movement of electrons. In electromagnets, the electrons flow along the electrical conductor. In a permanent magnet, the electrons are spinning (as electrons are wont to do) and this causes the magnetic field.

No moving electrons = no magnet.

The magnetic field of the Earth is caused by electrical currents flowing in the magma, and aligned roughly parallel to the Equator.

This alignment is probably caused by the inner core rotating slightly faster than the earth's skin. Due to the tidal drag of the Moon.

Does gravity have an effect on a magnet?

Yes, gravity does have an effect on a magnet, but it is typically very small compared to other forces acting on the magnet, such as magnetic forces. Gravity affects the entire mass of the magnet, pulling it towards the Earth, but the magnet's magnetic properties are typically more noticeable in everyday interactions.


What are the forces between a charge and a bar magnet?

The forces between a charge and a bar magnet are due to the interaction of electric and magnetic fields. Charges create electric fields, while magnets create magnetic fields. When a charge interacts with a bar magnet, the electric and magnetic fields can exert forces on each other, leading to attraction or repulsion between the charge and the magnet.


Where do magnet forces act?

Magnetic forces act between objects that have a magnetic field, such as between two magnets or between a magnet and magnetic material like iron. The forces are strongest at the poles of the magnets and decrease with distance.


If a refrigerator magnet can't hold apiece of paper against a refrigerator what forces are acting on it?

If the refrigerator magnet can't hold a piece of paper against the refrigerator, it may be due to the forces of gravity overcoming the magnetic force produced by the magnet. The weight of the paper pulling it down is greater than the magnetic force trying to hold it up.


Is a magnet in front of a refrigerator friction?

No, a magnet in front of a refrigerator is not an example of friction. Friction is a force that opposes the motion of an object when it is in contact with another object. The magnet sticking to the refrigerator is due to magnetic forces, not friction.

A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.


How is the world a magnet?

The magnet is in the world because magnetism is one of the fundamental forces of the universe, along with gravity.


Magnetic forces are the weakest at the poles of a mangnet.?

This statement is incorrect. Magnetic forces are strongest at the poles of a magnet, where the magnetic field lines are most concentrated. The strength of the magnetic force decreases as you move away from the poles towards the center of the magnet.


What forces act on a magnet?

The main forces acting on a magnet are magnetic forces. These forces can attract or repel other magnets or magnetic materials. Additionally, when a magnet moves in a magnetic field, it experiences a force known as the Lorentz force.
