Magazine Chapter 1: Q71P (page 1)
Figure 32-38 shows a loop model (loop ) for a paramagnetic material. (a) Sketch the field lines through and about the material due to the magnet. What is the direction of (b) the loop鈥檚 net magnetic dipole moment , (c) the conventional current in the loop (clockwise or counterclockwise in the figure), and (d) the magnetic force acting on the loop?
Short Answer
(a) The field lines through and about the material due to magnet are sketched.
(b) Direction of loop鈥檚 magnetic dipole moment is 鈥搙 direction.
(c) Direction of conventional current in the loop is counterclockwise.
(d) Magnetic force acting on loop is toward left.
Step by step solution
Understanding the concepts of magnetism:
By using the concept of para magnetism, energy stored in capacitor, energy stored in inductor as well as the rate of energy supply by the driving EMF, we can find the above quantities.
(a) Sketch the diagram:
Sketch the field lines through and about the material due to magnet.
(b) Explanation of direction of loop’s magnetic dipole moment:
For the paramagnetic material, the dipole moment is in the same direction as of . From the above figure, it is clear that points in the 鈥搙 direction.
(c) Explanation of direction of conventional current:
From the right-hand rule, since points in the 鈥搙 direction, the current flows counterclockwise from the perspective of the bar magnet.
(d) Explanation of magnetic force acting on loop:
The effect of is to move the material toward regions of larger values. Force is toward left directions.
