What is the eddy current formula used to calculate the induced currents generated by changing magnetic fields in a conductor?
The formula to calculate eddy currents in a conductor due to changing magnetic fields is given by: E -d/dt, where E represents the induced electromotive force, is the magnetic flux, and dt is the change in time.
What is the average induced emf in the loop?
The average induced electromotive force (emf) in the loop is the average amount of voltage generated in the loop due to a changing magnetic field.
What is the phenomenon that is induced by a changing magnetic field?
The phenomenon induced by a changing magnetic field is called electromagnetic induction.
What is the formula in electromagnetic induction?
The formula for electromagnetic induction is given by Faraday's law, which states that the induced electromotive force (emf) in a closed loop is equal to the negative rate of change of magnetic flux through the loop. Mathematically, it can be expressed as emf = -dΦ/dt, where emf is the induced electromotive force, Φ is the magnetic flux, and t is time.
What is the relationship between the induced voltage in a two-coil system and the magnetic field strength?
The induced voltage in a two-coil system is directly proportional to the magnetic field strength. As the magnetic field strength increases, the induced voltage in the coils also increases.

Can emf induced without an alternating magnetic flux?
No. EMF can only be induced in a wire by a varying magnetic flux. It does not have to be alternating, but it must be varying.
What is the relationship between the induced voltage in a two-coil system and the magnetic field strength?
The induced voltage in a two-coil system is directly proportional to the magnetic field strength. As the magnetic field strength increases, the induced voltage in the coils also increases.
What is the direction of the induced current in a coil when it is exposed to a changing magnetic field?
When a coil is exposed to a changing magnetic field, an induced current is generated in the coil. The direction of this induced current is such that it creates a magnetic field that opposes the change in the original magnetic field. This phenomenon is described by Faraday's law of electromagnetic induction.
How induced current produce?
when a conductor moves accross a magnetic field or when magnetic field moves with respect to a stationary conductor for current to be induced, there must be relative motion between the coil and the magnetic.

What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
How can one determine the direction of induced current in a circuit?
The direction of induced current in a circuit can be determined using Lenz's Law, which states that the induced current will flow in a direction that opposes the change in magnetic field that caused it. This means that the direction of the induced current will be such that it creates a magnetic field that opposes the original change in magnetic field.
What is the statment of lenz law?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
