What are the factors that determine the size and direction of the emf generated by the permanent magnet generator.?
number of conductors speed magnitude of the magnetic flux
A magnetic field does not interact with a?
A) stationary electric charge B) moving electric charge C) stationary magnet D) a moving magnet
How can we increase the magnitude of the magnetic field of an electric magnet?
Increase the magnitude of the electric current.
What happens when a magnet is kept stationary in the middle of the coil?
Not much.
How can electricity produce by using magnet?
Electricity is generated when a piece of conductive metal (such as copper) is passed through a magnetic field (or if the magnetic field is moved around the metal). A generator will have a copper wire in the center, surrounded by a magnet shaped like a torus (donut shaped, wire is in the hole in the middle). The wire is stationary. Electricity is generated when the magnet is spun (moving the magnetic field around the wire). This will generate an AC current (alternating current).
Where there is magnitude of the magnetic field around a permanent magnet greatest?
I am not sure but magnitude of magnetic field around its poles is greatest.
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
What does the direction of the magnetic field depend on?
it depends on the north of a magnet and the south of a magnet
Can you accelerate a stationary charged particle witha magnetic field or an electric field and please explain?
Yes.You must understand that magnetic fields induce electric fields 90 degrees out of phase (or perpendicular) to them, and vice versa.A charged particle will want to move one way or another when put within an electric / magnetic field, because the field will provide a push or pull on that particle in a specific direction.The easiest physical way to view this is with two magnets - imagine a small stationary magnet. If you take another magnet and hold it close to the stationary magnet, the second magnet will be creating a magnetic field that will either push the stationary magnet away or draw it closer. The same thing can be done by creating an electromagnet (push current through a coil of wire near the stationary magnet).
What is a stator magnet?
Stator magnet is the stationary part of a rotor system or a siren, found in an electric gen.,electric motor, siren, or biological rotors.
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.
How is a magnet field generated?
Anytime a particle experiences a change in charge or anytime charged particle travels, a magnetic field a generated.
