Opposite to OX. Along OX. Opposite to OY. Along OY. A field due to a long straight wire carrying a current I is proportional to. If a long straight wire carries a current of 40 A, then the magnitude of the field B at a point 15 cm away from the wire is. A negative test charge is moving near a long straight wire carrying a current. The force acting on the test charge is parallel to the direction of the current. The motion of the charge is:. A long straight wire carries a current of 35 A. The field due to a long straight wire carrying a current I is proportional to. A long straight wire carries a current i. A particle having a positive charge q and mass m, kept at distance x 0 from the wire is projected towards it with speed v.

Surveyors will tell you that overhead electric power lines create magnetic fields that interfere with their compass readings. Indeed, when Oersted discovered in that a current in a wire affected a compass needle, he was not dealing with extremely large currents. How does the shape of wires carrying current affect the shape of the magnetic field created? We noted earlier that a current loop created a magnetic field similar to that of a bar magnet, but what about a straight wire or a toroid doughnut? How is the direction of a current-created field related to the direction of the current? Answers to these questions are explored in this section, together with a brief discussion of the law governing the fields created by currents. Magnetic fields have both direction and magnitude. Hall probes can determine the magnitude of the field.

Surveyors will tell you that overhead electric power lines create magnetic fields that interfere with their compass readings. Indeed, when Oersted discovered in that a current in a wire affected a compass needle, he was not dealing with extremely large currents. How does the shape of wires carrying current affect the shape of the magnetic field created? We noted in Chapter 28 that a current loop created a magnetic field similar to that of a bar magnet, but what about a straight wire? We can use the Biot-Savart law to answer all of these questions, including determining the magnetic field of a long straight wire. What is the magnetic field at a point P , located a distance R from the wire? This means that we can calculate the net field there by evaluating the scalar sum of the contributions of the elements. Since the field decreases with distance from the wire, the spacing of the field lines must increase correspondingly with distance.

Taught by Bunty Kumar.

Moving charges experience a force in a magnetic field. If these moving charges are in a wire—that is, if the wire is carrying a current—the wire should also experience a force. However, before we discuss the force exerted on a current by a magnetic field, we first examine the magnetic field generated by an electric current.
