A very long straight wire carries a current I. A negative test charge is moving mear 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 square frame with side a and a long straight wire carrying a current i are located in the same plane as m shown in figure. The fram translates to the right with a constant velocity v. Find the emf induced in the frame as a function of distance x. The straight wire A B carries a current I. The magnetic field at the point P is. A conducting square frame of side ' a ' and a long straight wire carrying current I are located in the same plane as shown in the figure.

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. The field around a long straight wire is found to be in circular loops. The right hand rule 2 RHR-2 emerges from this exploration and is valid for any current segment— point the thumb in the direction of the current, and the fingers curl in the direction of the magnetic field loops created by it.

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. However, when a large current is sent through the wire, the compass needles all point tangent to the circle. Calculate the magnitude of the magnetic field at the other corner of the square, point P , if the length of each side of the square is 1 cm.
