Answer please. Thank you.
A time-varying magnet is necessary because it creates a changing magnetic field, which in turn creates a changing magnetic flux through the conductor. This changing magnetic flux induces an electric field and ultimately a current in the conductor, according to Faraday's Law of Induction.
No, a constant magnet cannot induce current in a conductor. This is because a constant magnetic field produces a constant magnetic flux, which does not create a changing electric field and therefore cannot induce a current.
The strength of the magnetic field is directly proportional to the induced current in a conductor. A stronger magnetic field will result in a larger induced current, while a weaker magnetic field will produce a smaller induced current.
Yes, the speed of the time-varying magnet can affect the induced current in a conductor. A faster-moving magnet will result in a larger induced current, while a slower-moving magnet will produce a smaller induced current. This is because the rate of change of the magnetic field is directly related to the induced current.
Yes, a conductor without any current flowing through it can still induce a current in another conductor if it is placed in a changing magnetic field. This is known as mutual induction and is the principle behind transformers and other types of electromagnetic devices.
