A magnetic field is generated whenever a current is passing through a wire.
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.
An electromagnet produces a magnetic field because when an electric current flows through a coil of wire, it creates a magnetic field around the wire. This magnetic field is stronger when the current is stronger and when the coil has more turns.
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
The magnetic field of an electromagnet is similar to the magnetic field of a permanent magnet. Both exhibit magnetic properties and can attract or repel other magnetic materials. The strength of the magnetic field of an electromagnet can be controlled by adjusting the electrical current flowing through it.
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
The magnetic field for an electromagnet is created by the flow of electric current through a coil of wire, which generates a magnetic field around the coil.
When a compass gets near an electromagnet, the magnetic field produced by the electromagnet interferes with the Earth's magnetic field, causing the compass needle to align with the electromagnet's field instead. This phenomenon is known as magnetic deflection.
It doesn produce electricity. It uses electricity and shows magnetic properties.
An electromagnet creates a magnetic field when an electric current passes through a coil of wire, which magnetizes the core of the electromagnet. This magnetic field allows the electromagnet to attract or repel other objects that contain iron, nickel, or cobalt.
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.
When you turn on the current in an electromagnet, it induces a magnetic field around the magnet. This magnetic field allows the electromagnet to attract or repel other magnetic objects or influence nearby currents. The strength of the magnetic field can be adjusted by changing the amount of current flowing through the electromagnet.
