## Experiment II Magnetic Fields due to Currents

1 Physics 202, Lecture 13 Today’s Topics Sources of the Magnetic Field (Ch. 30) Calculating the B field due to currents Biot-Savart Law. magnetic field (B) as a function of I and the distance (r) away from the wire is given by: Figure 1: B field near a current-carrying wire. where -7 Tm/A, I is in Amperes, r is in meters, and B is in Tesla.. magnetic field due to a nearby magnet or current-carrying wire. In this paper, we present a series of simple activities Once the circuit is closed, the magnetic field due to the wire will point east-west near the compass and the needle will Fig. 2. With no current in the wire, the compass points north. Fig. 3. When 0.314 A is run through the wire, the compass deflects by approximately 20o.

## Off-axis magnetic field due to a current loop in cartesian

Sketch the magnetic field pattern due to current-carrying rod. the permanent magnets and their combined magnetic field The two fields acting in the same direction combine to give a stronger field. Interaction between magnetic field of a permanent magnet and an electromagnet (current-carrying wire) Explain in terms of magnetic field interactions.. The direction of the magnetic field at a distance from the wire is tangential to a circle of radius ,as shown. Since the magnetic field due to all current elements at P are parallel to the z-direction, the field at P due to a wire, the.
