Can a static magnet induce an emf in a stationary coil of wire?
No. In order to induce an EMF, the coil and the magnet must be moving in relation to each other.
When a strong magnet is passed rapidly through a coil of wire what is true?
The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.
What is used to test permanent magnet generators?
you get it up to operating speed and see if it delivers full load voltage and current. if it has been severely overloaded the permanent magnet can be discharged causing the output to be low
The magnitude of the voltage induced in a conductor moving through a stationary magnet field depends on the?
The speed of the conductor through the magnetic field, which translates into the number of magnetic lines of force the conductor can cut per unit time, will determine the magnitude of the voltage induced in the conductor. As an additional factor, if a longer piece of wire can be moved through the magnetic field, it will induce more voltage as well. The more speed we can put on the conductor, and the more of the conductor we can move through the magnetic field, the more voltage we can induce in the conductor.
What happens when the magnet stops moving in a DC motor?
Nothing. The motor is not doing work. A voltage needs to be switched between the coils for it to go.
How does a magnet create electricity?
It is not the magnet alone, but the movement of a conductor (wire) in a magnetic field will induce a voltage (and a current, if it is connected in a circuit).
What is the key using a magnet and a conductor to induce a current in the conductor?
A changing magnetic field, in the conductor, can induce a voltage (and, under the correct conditions, that in turn will result in a current). In the case of a permanent magnet, either the magnet or the conductor has to move.
Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across the wire.
Can a round magnet produce electricity if it's rotating?
The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
Can a static magnet induce an emf in a stationary coil of wire?
No. In order to induce an EMF, the coil and the magnet must be moving in relation to each other.
What is a magnet pole in a simple generator?
Induce current in the generator windings.
What is key when using a magnet and a conductor to induce a current in the current?
Motion

What does the combination of a magnetic field and a coiled wire create strong magnet week magnet or neutral magnet?
it creates a very strong magnet A+ users
What are two ways to induce a larger electric current when you move a magnet in a coil of wires?
answer me or i will tell every one u suck!!!!!!!
What would happen to the voltage and the magnet is withdrawn from the coil?
the voltage increases
