Can an electric current be used to deflect a compass needle?
Yes.
Can a electric current be used to deflect a compass needle?
Yes,
An electric current cannot be used to deflect a compass needle?
Yes, it can.
Can an electric current be used to affect a compass needle?
Yes. Any electric current is surrounded by a magnetic field.
What rule is used to find out polarity of a current carrying solenoid?
right hand rule is used to find out the polarity of current
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.
Why pmmc used for DC only?
Because in the coil DC current follow easly and pmmc meter is making with coil and AC current is not follow in coil so we used the pmmc only fpr DC current.
Can a electric current be used to deflect a compass needle?
Yes,
Can an electric current be used to deflect a compass needle?
Yes.
What purposes does an insulator serve?
An insulator is used to isolate current carrying components from conductive non current carrying components.
An electric current cannot be used to deflect a compass needle?
Yes, it can.
Can a magnet cause an electric current to flow through a wire?
You obviously cannot more a magnet through a coil in the direction of the current, because the magnet must move, axially, along the length of the coil, while the current moves radially, around the coil. However, if you move a conductor within a coil carrying a d.c. current, then the magnet will induce a voltage into that coil which will oppose the voltage applied to the coil.
What happens when a wire is looped into a coil?
When you wind a current carrying wire into a coil, it causes the concentration of the magnetic field line to intensify. Depending on which pole of the magnet is in the up position, the wire will move towards or bend away from it.
What is coil galvanometer meter and its application?
Moving coil galvanometre is a device which is used to detect current in a curcuit.
Can an electric current be used to affect a compass needle?
Yes. Any electric current is surrounded by a magnetic field.
What rule is used to find out polarity of a current carrying solenoid?
right hand rule is used to find out the polarity of current
What is a Tesla coil used for?
to generate electricity to demonstrate the ac current is harmless
