Move wires rapidly through the magnetic field so that they "cut" the field lines will create an electric current in the wires.
This is the method used in alternators, generators, magnetos, and read heads on disk drives and tape recorders.

∙ 8y agoThe commonest use - is as an electromagnet. A wire carrying current, wrapped around a metal 'core' produces a magnetic field - but only while the power is present. This makes an electromagnet - a common 'tool' in a scrapyard or processing plant.

∙ 8y agoIf you move a conductor - e.g., a wire - through the magnetic field, a voltage will be induced in the conductor. If there is a closed circuit, a current will flow.Note that the current will induce a magnetic field which counters the direction of the movement - therefore, work is required to keep the wire moving, and obviously, energy is conserved.

How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
What are all the sources of magnetic fields?
the poles (north and south) create the magnetic fields Magnetic fields are, in the end, the result of the movement of electrostatic charges. Any charged particle will create a magnetic field around its path of travel. (And, conversely, it can be affected by an external magnetic field.) It could be the separation of charges that creates a magnetic dipole, as in an atom. (Positive nucleus with the negative electron cloud about it.) It could be the movement of electrons in a conductor. (Electric current flow in a wire.) One of the four basic forces in the universe is the electromagnetic force. Not the magnetic force, but the electromagnetic force. If there's no moving charge, there's no magnetic field. The two phenomenon are intrinsically connected.
Creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields.
What is meant by electric and magnetic field?
A magnetic field is a area in which magnetic objects are pushed or pulled. It is caused by the alignment of parts of atoms.A field of force associated with changing electric fields , as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges. Most magnets have magnetic fields as a result of the spinning motion of the electrons orbiting the atoms of which they are composed; electromagnets create such fields from electric current moving through coils. Large objects, such as the earth, other planets, and stars, also produce magnetic fields. See Note at magnetism.
How are magnet fields and electric fields alike?
Both act only on charged particles (ions, protons, or electrons). ?However, an electric field (which generates an ELECTRIC FORCE) acts on a particle in the same direction as the field, given by the equation:F(vector) = q*E(vector)The resulting force vector is in the same direction as the field vector (for positive charges).A magnetic field generates a force ONLY on a MOVING charge, and ONLY if the charge is moving non-parallel to the magnetic field:F(vector) = q*v(vector) x B(vector)Because of the cross-product, the magnetic force is a direction perpendicular to the velocity and magnetic field vectors (use the right hand rule to figure out the direction of magnetic force). ?The particle will still have momentum from its initial velocity, so an applied magnetic field will (pretty much) always make the particle move in a curved path.
Does electric current create magnetic fields?
Yes, electric current does create magnetic fields
What is magnetic in electromagneticism?
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
How do the electric and magnetic field of an electromagnetic wave regenerate each other?
No. Current flow creates electromagnetic fields in space. Electromagnetic fields, in turn, can create current flow in conductors. The electric fields do not directly create magnetic fields, nor do magnetic fields directly create electric fields.
How are magnetic fields and electric current related?
The two are related because an Electric current produces Magnetic Fields
What is Created by vibrations in electric and magnetic fields?
Vibrations in electric and magnetic fields create electromagnetic radiation.
How are moving electric charges related to electric and magnetic fields?
Moving electric charges create electromagnetic fields.
What creates magnetic fields?
Basically moving electric charges will create a magnetic field.
What type of fields are created by an arrangement of electric charges or a current?
Magnetic fields can be created by charges or the flow of current.
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.
What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.
What is the definition of the word electromagnetism?
Electromagnetism is the interaction of electric currents or fields and magnetic fields. It is the magnetic field created when an electric current passes through a wire, and is extremely useful because the magnetic effect stops as soon as the current stops.
Electric fields and magnetic fields are both present near a wire carrying current?
False, electric fields and magnetic fields do not often occur together.
