Consider the force on a current carrying conductor in a magnetic field (see figure), how do we think the displacement of rod AB will be affected if
(1) current in rod AB is increased;
(2) a stronger horse-shoe magnet is used; and
(3) length of the rod AB is increased?
(1) current in rod AB is increased;
(2) a stronger horse-shoe magnet is used; and
(3) length of the rod AB is increased?
1. If the current in the rod is increased, then the rod will be deflected .
2. If a stronger horse-shoe magnet is used, the rod will also be deflected due to the in the magnetic field.
3. If the length of the rod AB is increased, Deflection of rod in a magnetic field .
