A magnetic field is generated whenever a current is passing through a wire.
An electromagnet produces a magnetic field when current is passed through it wire winding.
The motion of electric charge or current..
The magnetic field reverses direction.
Yes. A steady current will produce a magnetic field, B= uI/r
a magnetic field
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
An electromagnet produces a magnetic field when current is passed through it wire winding.
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
to produce magnetic field to move the piston of the doorbell
a magnetic field
An electromagnet requires only two parts, a core of ferro-magnetic material and wires winding around it. The wires magnetize the core when current flows through them, and the core then creates the magnetic field which the electromagnet is intended to produce.
Electrons move in orbit and thus produce a magnetic field like a electromagnet.
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
No. Venus has no magnetic field.
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.

The magnetic field. If it's an electromagnet, the electromagnetic field.
