What will be the effect on a current carrying coil placed in stationary permanent magnetic field?

Nothing because there has to be kInetic energy to convert to electrical energy therefore there is no charge not even a minus charge.
Hope this helps, if it does Please recommend me it would be much approciated

Can a magnetic field exert a force on a stationary current-carrying wire?
Surely but current direction has not to be parallel to magnetic field. Force on the wire = B I L sin@ When @ is zero, ie parallel then F = 0 If @ = 90 then force will be max. F = B I L Here L is the length of the current carrying conductor
What is the cause of a magnetic field about a current-carrying wire?
The cause is the current.
What is true of permanent magnets?
Permanent magnets contain a current-carrying wire.
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
Which are defected by electric and magnetic fields?
Any charged particle in motion especially not parallel to the magnetic field, current carrying conductor kept inclined or perpendicular to the magnetic field would get deflected. As far as electric field is concerned, even stationary charges would be displaced.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
In a current carrying conductor what exist around it?
a magnetic field
Does coil of wire carrying a current have a magnetic field?
yes
What is used to turn the pointer of a galvenometer?
The pointer on a galvenometer moves due to magnetic force between the current carrying coil in the pointer assembly and the permanent magnet surrounding that coil.
Will a copper wire not carrying a current be attracted to a magnet?
No, a copper wire that is not carrying a current will not be attracted to a magnet. Copper is not a magnetic material, so it does not interact with magnetic fields in the same way that magnetic materials like iron or nickel do.
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
