What is true about electric currents and magnets?
Sort of... In permanent magnets, magnetism is due to the movement of electrons around their atoms. Each atom is a small magnet, and there are more atoms aligned in one direction than in the other. If you consider the electron orbiting around the atom, or "spinning around its axis" as a "current", then yes.
How do magnets interact with copper to create electrical currents?
When a magnet moves near copper, it creates a changing magnetic field. This changing magnetic field induces electrical currents to flow in the copper, generating an electric current. This phenomenon is known as electromagnetic induction.
How does the interaction of magnetic fields and electric currents contribute to what makes a magnet work?
The interaction of magnetic fields and electric currents creates a magnetic force that aligns the atoms in a material, making it magnetic. This alignment allows the material to attract or repel other magnets, which is what makes a magnet work.
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.
Do permanent magnets produce electric currents?
Permanent magnets do not produce electric currents on their own. However, when a permanent magnet moves near a closed loop of wire or coil, it can induce an electric current in the wire due to electromagnetic induction.
What magnet is made by electric currents?
All electric currents create magnetic fields. If you wind wire into a coil and pass current through the wire, that is an electromagnet.
Can a magnet be made with electric currents?
theres no answer
Can be produced by electric currents going around?
Sending electricity though a copper wire wrapped round an iron core will create an electro-magnet.

can electrical currents can be used to create a magnetic field.?
Move the magnet inside a coil of wire.

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.
How can a magnet be used to create an electric current?
An electrical current will flow in a conductor, when a magnet is moved next to a conductor - or when the conductor is moved next to the magnet.
What create magnet force?
Magnetic forces can be caused by an electric current. Or they can be caused bymagnetic domains aligned correctly. These domains are magnetic moments created by moving atoms in the material who have an electric dipole (usually).
Do permanent magnets produce electric currents?

How does a magnet contribute to the functioning of a speaker?
A magnet in a speaker helps create sound by interacting with an electric current to move a diaphragm, which produces vibrations that create sound waves.
