Question: Figure 1. A lat plane conductor carries a uniform current into the page. The sketch shows part of a large slab of conductor that is carrying a current that is uniformly distributed across its width (laminations in the conductor are not shown, but are needed to make the current uniform). The current per unit horizontal length has magnitude 23.9A cm The X's in the sketch show that the current is in the direction into the page. However, while the "X's in the sketch are discrete, the current distribution may be considered as continuous. The slab is so wide that edge efrects may be ignored, and this question only concems points far from the edges. Part 1) What is the direction of the magnetic field 1. Just above the conductor? Right 2. Just below the conductor? Left 3. In the middle of the conductor? Near zero Part 2) The current per unit length (current into the page per displacement in the horizontal direction) is k magnitude of the magnetic field just above the conducting slab? 23.9 amperes per centimetre [NB: current per unit length, not current density]. What is the Part 3) A second, simlar slab is placed above the first, carrying the same current density k but in the opposite direction, Le. out of the page. The separation is so much smaller than the width of the slab that edge effects may be neglected. What is the magnitude of the force per unit area between them? (Substitute for B from part 2 to eliminate B from your answer.) F/A- N m 2

Explanation / Answer

According to Right hand rule, the magnetic field lines produced by a current carrying wire will be oriented in the same direction as the curled fingers of a person's right hand with the thumb pointing in the direction of the current flow.
