What is the function of a field magnet in an $AC$ generator?

When an electric current flows through a conducting wire,what is produced in the region around it?

Which of the following appliances cannot be connected in a $15\, A$ current line?

Give the direction of induced current in the following figure:

To find the direction of the magnetic field around a current-carrying conductor,we use Fleming's left-hand rule.

Describe the activity that shows that a current-carrying conductor experiences a force perpendicular to its length and the external magnetic field. How does Fleming's left-hand rule help us to find the direction of the force acting on the current-carrying conductor?
