Why the the reading on the newton meter increases when a current passes through the coil?
because it becomes more magnetic therfore it the pull on the coil will increase
What would happen if the current passing through the coil was too large?
The coil offers some amount of Resistance to the flow of Electric current through the coil. The Resistance of the coil depends on the material used to make the coil and the thickness of the coil wire ( its gauge ) When a current flows through the coil, the voltage drop across the coil and the Power dissipated in the coil both are proportional to the magnitude of current and the coil resistance. Normally the coil is rated to carry certain current and dissipate certain amount of power without causing any damage. If a large magnitude of current flows through the coil beyond its rating , the voltage drop across the coil and the power dissipation in the coil both increase substantially causing over heating of the coil. This can damage the coil and may result in burning of the coil
What voltage should be applied to make an electromagnet?
The strength of the electromagnet depends on the magnitude of the current in the coil around it.The voltage required is only what produces the desired current in the coil. Since the coil is nothing butwire, the resistance is quite low, and a relatively small voltage produces a relatively large current.
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.
What would happen to the voltage and the magnet is withdrawn from the coil?
the voltage increases
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
Why the the reading on the newton meter increases when a current passes through the coil?
because it becomes more magnetic therfore it the pull on the coil will increase
What is most likely to happen if you where to place a magnet in a coil of current carrying wire?
It would spin.

What will happen if you pass dc current through a single coil?
If dc current is passed through a single coil, it is going to remain constant.
What has to happen around a coil of wire to generate an induced current?
pass a magnetic field through the coil of wire.
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
Why the current coil of wattmeter has more thikness wire than pressure coil?
Current coil carries the current.
What is current coil and voltage coil?
The current coil is one through which the current of source can pass. This coil is connected in series. The voltage coil is connected parallel to the applied voltage. In the current coil the quantity of current flowing is proportional to the current flowing in load while in the voltage coil, current flowing is proportional to applied supply voltage. The voltage coil current is independent of current flow in load. For a complete understanding, please refer to a watt meter diagram.
What is a coil of wire with a current called?
current carrying coil
What will happen to the current if the magnet and coil were not moving?
I assume you mean in a setup similar to an electrical generator. Here, current is ONLY produced if there is relative movement, between the magnet and coil. Without movement, there will be no current.
What voltage should be applied to make an electromagnet?
The strength of the electromagnet depends on the magnitude of the current in the coil around it.The voltage required is only what produces the desired current in the coil. Since the coil is nothing butwire, the resistance is quite low, and a relatively small voltage produces a relatively large current.
