Yes, but it would usually not have much practical use if the magnetic field flipped around all the time.
An electromagnet.
increase the current on the electromagnet
That is an electromagnet.
Yes, cast iron can be made into an electromagnet by wrapping it with a coil of wire and passing an electric current through the wire. When the electric current flows through the coil, it creates a magnetic field in the cast iron, turning it into an electromagnet.
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
Alternating current and static electricity. Pulses of current made via piezo electricity would be called d.c.
An alternating current (AC) is a type of electric current that changes direction periodically. It moves back and forth in a cyclic manner, typically in a sinusoidal waveform. AC is commonly used in household power supply systems and many electronic devices.
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
Electromagnet.
Nikola Tesla is known as the father of current. Tesla is made contributions to the modern alternating current of electricity.
An electromagnet is a temporary magnet made using electric current running around a metal core. The magnetic field can be turned on and off by controlling the flow of current. Electromagnets are commonly used in various applications such as electric motors, MRI machines, and speakers.
An electromagnet is made by an electric current flowing through wires. The magnetic field is created when the current passes through the wire, generating a magnetic field around it. This magnetic field can attract or repel other magnetic objects nearby.
