What is the process by which electric current is generated by placing a wire in a field?
electromagnetic induction
What is the process by which electric current is generated by a placing a wire in a magnetic field?
electromagnetic induction
An electric current can be genrated by moving a wire coil in a magnetic field?
Yes. That is how it is done.AnswerNo, it's a voltage, not a current, that is generated.
What will happen if you place a magnetic compass in an electric curcuit?
The compass will align itself with the magnetic field generated by the current flow through the wires.
Why is heat generated across a resister when electric field is applied?
An electric current contains energy; so does an electric field. When a current flows through a resistor, part of the electrical energy will be wasted - i.e., converted to heat. You can think of this as if some of the electrons crash into atoms, instead of continuing on their way.
Where does the earths magnetic field originated from?
The Earth's magnetic field is generated by the the Earth's spin and the fact that it has molten iron in its core. When convecting molten metals spin they generate electric currents and with these a magnetic field.
The Earth's magnetic field is generated in?
the outer core.
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 is the process by which electric current is generated by placing a wire in a field?
electromagnetic induction
How is an electromagnet wave generated?
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
Is earth has its own electric field?
Earth has its own magnetic field which is emitted from iron core. This protects us from harmful rays. But it does not have an electric field
The Earth's magnetic field is generated by the dynamo effect in the?
the crust
