Hello!
How can an electric current be produced in a conductor?
What is Electromagnetic Induction?
*Please refrain from asking questions until the end of each slide, this will help us not to have many interruptions. We will ask at the end of each slide if anyone has any questions.

What are the characteristics of solenoids and electromagnets?
A relationship between
electricity and magnetism is called
electromagnetism
.

What are
solenoids
and
electromagnet
.
A reagon around magnets material or a moving electric charge within with each the force of magnetism acts
When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy
An electric current turns the pointer of a galvanometer.
An electric motor transforms elctrical energy into mechanical energy
