Question
Student ID # Date: Section Laboratory 8- Magnetic Fields Part 1 (1) Draw magnetic field lines on the following diagrams. [0.75 (2) Describe the Right Hand Rule for solenoids. [o.25) (3) A galvanometer is a very sensitive10.251 (4) An electron moves in the plane of this paper toward the top of the page. A magnetic field, also in the plane of the page, is directed toward the right. What is the direction of the magnetic force on the electron? [0.25] a. Toward the top of the page b. Toward the bottom of the page c. Toward the left edge of the page d. Toward the right edge of the page e. Upward out of the page f. Downward into the page 155
Explanation / Answer
Solution;
2)
An electric current passes through a solenoid, resulting in a magnetic field. When wrapping the right hand around the solenoid with the fingers in the direction of the conventional current, the thumb points in the direction of the magnetic north pole. An electric current passes through a straight wire.
3)
Electric device
4)
Magnetic force, F = (v x B)
Direction : upward out of the page
