What happens when a current stops flowing through the wire of an electromagnet?
magnetic fieldOnly
What can decrease the magnetic field around a wire?
Only decreasing the magnitude of the current flowing through the wire can.
Why does the compass respond when it is near a electrical wire with current flowing through it?
Because electricity gives off a magnetic field.
Why can't a compass might not point north if its placed near a wire with a current?
Current flowing through a wire induces a magnetic field, causing the compass to point away from "magnetic north" and point in a different direction.
What will happen to the electromagnet when current flows in the wire around it?
A coil of wire in which current is flowing is an electromagnet. If to that arrangement you add an iron core, then the magnet will get stronger.
Is an electromagnet a coil of wire with current flowing through?
Yes.
Would increase the strength of an electromagnet?
More coils of wire around the magnetic material.More current through the wire in the coil.Increasing the current flowing through the wire Increasing the number of loops of wireputting a piece of iron inside the loops of wire apex :)Increasing the current flowing through the wireIncreasing the number of loops of wire
Is there actually current flowing through the return wire?
Yes, there is a current flow through he return wire in a closed circuit. The only time there is no current flow through the return wire is when the circuit is open.
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
What happens when a current stops flowing through the wire of an electromagnet?
magnetic fieldOnly
What can decrease the magnetic field around a wire?
Only decreasing the magnitude of the current flowing through the wire can.
If more electrons were flowing through a wire what would be increased?
If more electrons were flowing through a wire, the thing that would be increased would be the current. This is the flow of the carriers of electrical charges.
What does a inductive ammeter do?
It measures current by creating a coil around the current carrying wire. Current flowing in the wire induces a current in the amp-meter proportional to the current flowing in the wire.
How could you prevent too much current from flowing through a wire?
by resistor installation
What occurs because alternating electrical current flowing through a wire creates an electromagnetic field around the wire?
shorts
Is it dangerous for a earth wire to be hanging in the kitchen?
No. An earth wire (commonly called a ground wire) has no current flowing through it. It is simply a wire connected to the ground to discharge electrical current in a circuit.
How can an electric current be kept flowing through a coil of wire?
By applying an electrical current constantly or by using a superconducting material.
