What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
Is a toothpick a part of an electromagnet?
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
What happens when a current stops flowing through the wire of an electromagnet?
magnetic fieldOnly
How does a doorbell use an electromagnet?
The electromagnet is only part of the mechinism the whole item is called a solenoid which has a magnetized rod inside the electromagnet when 24 volts is applied the solenoid springs out of the coils of the electromagnet striking the bell. When released the rod returns by use of a spring and strikes another bell. Ding, Dong.
How is electric energy converted into mechanical energy?
Through an electromagnet- most commonly when the electromagnets are part of an electric motor.
What happens when a part of a parallel circuit is disconnected?
current decreases and resistance increases
When would an electromagnet stop working?
An electromagnet would stop working if the electrical current flow is interrupted or if the power supply is disconnected. Additionally, if the coil overheats, it can damage the insulation and cause the electromagnet to fail.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
What is it called when you wrap a wire around an iron bar and connect it to a battery?
It is called an Electromagnet, when disconnected, it loses it's magnetism.
What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
What happens when the electric current is reversed on am electromagnet?
When an electric current is reversed in an electromagnet, the magnetic field also reverses.
What happens when you disconnected the wire from the dry cell?
when the wire is disconnected from the dry cell you feel not hot
Suppose you wrapped an iron bar with wire and connected the ends of the wire to a battery what is this device called what would happen to this device if you disconnected the battery?
This would be an Electromagnet...... If the battery is disconnected, then the iron bar will become a permanent magnet.
What is the central part of an electromagnet?
A ferrous core.
Is a toothpick a part of an electromagnet?
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
What happens when a compass is placed next to a electromagnet?
the arrow goes to the magnet
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
