To apply the Biot-Savart law to find the magnetic field produced on the z axis from current elements in the xy plane. In this problem you are to find the magnetic field component along the z axis that results from various current elements in the xy plane (i. e., at z=0).

The law of Bio Savart is used to show the magnetic intensity because of the availability of magnetic current.

Explanation:

In physics, explicitly electromagnetism, the Biot–Savart law is a condition portraying the attractive field produced by a consistent electric flow. It relates the attractive field to the extent, heading, length, and closeness of the electric flow.

The Biot Savart Law expresses that it is a scientific articulation which shows the attractive field delivered by a steady electric flow in the specific electromagnetism of material science. It tells the attractive field toward the greatness, length, heading, just as closeness of the electric flow.

what type of charge does it have? negative

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
