Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
What happens when there is a change in the magnetic field in a closed loop of wire?
It produces a current.
What does current-carrying wire mean?
It means that a current flows through the wire.
How could you change the direction in which a compass needle points using a cell and a piece of wire?
The compass will react to magnetic fields, and magnetic fields are caused by currents. Therefore, holding a current-carrying wire close to the compass is enough to change the direction in which it points.The compass will react to magnetic fields, and magnetic fields are caused by currents.

What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.

How does the charge on a wire change when an electric current flows in the wire?
2 plus 2
What happens to the current carrying capacity of a conductor when you change the frequency from 50hz to 60hz?
The current caring capacity of a wire is based on the physical size of the wire. The larger the diameter of the wire the more amperage the wire is allowed to carry.
What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.
What happens when there is a change in the magnetic field in a closed loop of wire?
It produces a current.
What happen to the magnetic field of a wire when change the direction of the current in the wire?
Direction of the magnetic lines too would get changed

Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
Can you list three ways you can change the current in a circuit?
Increase, decrease, or remove the load <<>> Change the voltage and the current will also change in direct proportion, Ohms law.
What happens to an electric current when the wire is made smaller?
Electric current as we usually describe it is the flow of electrons. Current is caused to flow by voltage, which can be looked at as "electrical pressure" that forces electrons to move. Currents can be made smaller or larger by decreasing the voltage across a fixed amount of resistance. As resistance is the quality of "resisting" or "limiting" current flow, we can change resistance to change current. For a give voltage, if we increase the resistance, we can make the current smaller, and if we decrease it, we can make current larger. In electronics, voltage equals current times resistance. E = I x R Also true is that current is equal to voltage divided by resistance. I = E/R As current equals volts divided by resistance, if we change one of them without changing the other, current will change. And in increase in voltage (with no change to resistance) will cause current to go up. The opposite is also true. Also, if we increase resistance (with no change in voltage), current will go down. And the opposite is true here, too.
What is effect of voltage and current by changing the length of wire?
By changing the length of wire, say reducing it, the resistance will drop and that will increase current flow but the voltage is less likely to change V=IR.
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.
