Why is it necessary to have some form of controlling couple in the moving coil galvanometer?
To stop the moving coil from movement as if there wasnt any opposite couple the coil will complete rotating and this wouldnt help measurement.
Where do you use magnet to generate energy?
Magnets are used in generators. A magnet is rotated by something, e.g. a wind turbine, and the magnet turns inside a copper coil which generates electricity. It is the opposite of a motor.
How does a coil act?
a coil acts as an electromagnet.
How do I know the direction of the torque acting on coil whether its vertical or horizontal?
To know the direction of the torque acting on the coil, whether the coil is vertical or horizontal, you will compare the direction of the magnetic force or its rotation to the direction of the coil. If the coil is vertical and the magnetic force is in the direction of the coil rotation, then the direction of the torque will be the same.
Is a coil a conductor?
heater coil is good conductor of electricity

When the chromosomes coil up and become visible and the centrioles go the opposite sides of the cell?
prophase
Where is the coil on 2000 Ford Focus?
opposite end of the spark plug wire from the spark plugs
What is the purpose of the permanent magnet in the moving coil meter?
The purpose of the permanent magnet in the moving coil meter is to measure electrical current. The coil will have a magnetic field which will react to the magnetic field of the permanent magnet. Since opposite poles attract, it will cause for the coil to move.Ê
How do you connect battery and coil in a 1950 dodge wayfarer with positive ground?
make sure the coil is a positive grounded coil, most are negative ground. battery just hooks up opposite to usual the coil is the only thing u need to make sure of
Where is ignition module on 1991 corolla?
Under the dizzy cap, a black square opposite the coil, it has 3 wires
When an Electric motor or Generator is switched on what will make the coil turns the opposite way?
if it is a capacitor start and run motor, this is because of shorted capacitor
Michael Faraday's experiments with an iron ring?
Two coils of insulated copper wire would round a soft iron ring. Coil A on the left side wre connected with a battery and a switch and on the other side of the ring coil B is attached and a compass attached within the wire opposite coil B
What is the emf induced at zero field current.and what does it signify?
EMF is the voltage across a coil (or motor) due to changes in the magnetic field. If you change the current the coil will generate a voltage (in the opposite direction of the current). So it is not the field but the change that matters.
What happens when a magnet is pushed into the coil during an experiment to demonstrate electromagnetic induction?
-- While the magnet is moving, there is a voltage between the ends of the coil and, if there's any connection between the ends, then there's a current in the coil. -- When the magnet stops moving, all of that goes away. -- When the magnet is pulled out, it all happens again, but with the opposite polarity.
Does adding electric currents to something that is already magnetized increase or decrease the power of the magnet?
By 'adding electric currents', you are presumably talking about passing a d.c. current through a coil wound around a magnet?First of all, you cannot increase the flux density of a magnet beyond saturation, regardless of the current or number of turns that make up the coil. Whether on not you increase or reduce the flux density depends on the polarity of the coil compared with the polarity of the magnet; if they are opposite then, yes, you can demagnetise the magnet and, in fact, remagnetise it in the opposite direction.
What are the different ways to induce current in a coil?
Different ways to induce current in a coil are as given below:(1) If a magnetic field is changed round a coil then an induced current is set up in the coil. It can be done by taking a bar magnet and bringing it closer to the coil or taking it away from the coil.(2) If a coil is moved in a magnetic field, then again an induced current is set up in the coil.(3) If a coil is rotated in a uniform magnetic field, it may also cause an induced current in the coil.(4) If we take two coils and insert them over a non conducting cylindrical roll then on changing current flowing in one coil, an induced current is obtained in the other coil.CommentYou don't induce a 'current' into a coil; you induce a voltage. If that coil is open circuited, then no current will flow. If, on the other hand, the coil is connected to a load, or its opposite ends short-circuited, then the induced voltage will cause a current to flow. Remember, current will only flow if there is a load, or short circuit, and the value of the current will depend upon the value of the induced voltage and the resistance of the load or short circuit.
