Lesson: Magnetic Fields Produced by Electric Currents Physics • Third Year of Secondary School

Join Nagwa Classes

Attend live Physics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe the magnetic field that is produced by a wire carrying an electric current.

Students will be able to

recognize that an electric current in a wire will produce a magnetic field around the wire,
recognize that the larger the electric current in the wire, the stronger the magnetic field produced,
recognize and draw the shape of the magnetic field lines of the magnetic field produced by a current-carrying wire,
identify the direction of the magnetic field near to a current-carrying wire,
state what a solenoid is,
recognize that the magnetic field produced by a solenoid can be increased in strength by adding a core of a magnetic material.
