What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
What has to happen around a coil of wire to generate an induced current?
pass a magnetic field through the coil of wire.
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 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.
Is a solenoid a coil of wire that has a current?
YESA solenoid is a coil of wire, which turns into a magnet when a?current?flows through
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.
What is a magnet created when electric current flows through a coil of wire?
A magnet created when electric current flows through a coil of wire is called an electromagnet.
Does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
How does a generator produce electric current?
A generator moves a coil of wire through a magnetic field and that induces a current in the coil .
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
Why inductor is only used for ac power supply?
Because inductance is only related to alternating current. Direct current doesn't induce eletrical current on a secondary coil placed on a primary coil, because there is no frequency generated by direct current, and all you get is a single electrical current flowing through the wire without interfering with a coil placed near to the primary coil. What makes all the difference is the cycles per second that only alternating current can generate.
Why if the same current flows in a wire coil and a single wire loop the magnetic field inside the coil is stronger than the field inside the loop?
why, if the same current flows in a wire coil and a single loop, the magnetic field inside the coil stronger than the field inside the loop
