Questions
A permanent magnet cannot be used in the electric bell, why?
Write two uses of the solenoid.
What is a Solenoid? Draw a picture showing the magnetic field developed around a solenoid.
Draw the magnetic field developed around a straight current-
carrying wire.
How can the magnetic field produced around straight current carrying be demonstrated by using iron dust, cardboard, and conducting straight wire? Explain it.
Define magnetic flux.
What is the magnetic effect of current?
Maxwell's right-hand grip rule to find the direction of magnetic field lines of force around a solenoid. Explain.
Maxwell's right-hand thumb rule shows the direction of the magnetic field produced when an electric current flows through a straight wire. Explain.
Draw the magnetic field lines around the current-carrying straight wire and solenoid.
