Distinguish between a common bar magnet and an electromagnet. What is the cause of a magnetic field about a common bar magnet? What is the cause of a magnetic fields in an electromagnet?How are electric motors and electric generators similar? Different? How do they each make use of electromagnetic induction?What does a transformer do? How does it make use of electromagnetic induction? What correction do you make to a friend who states that a step-up transformer boosts energy, while a step-down transformer reduces energy in a circuit?
Homework Answers
A common bar magnet is an object made from a material that is magnetized and has its own magnetic field. The magnetic field is permanent at all times.
An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it .
A common bar magnet is a magnet because of the orientation of its domains. Domains are the small magnetic field present in the crystalline structure of ferromagnetic materials.
in an electromagnet, when current flows the wire it produces a magnetic field.
