We want to find the magnetic field at one corner of a square; the field is produced by currents that are located at the other three corners of the square. (See drawing.) The square is in the x-y plane and the currents are flowing parallel to the z axis. We define a positive current as one flowing in the + k direction. 13 The first current, of 7.15 A, is located 3.03 cm along the x axis, that is, at...
How can we find the magnetic field using Biot-Savart's law? 3. Calculate the magnetic field at point P due to the two wires shown below. The current 110 A flows in the wire AP, and a different current 2 20 A flows along the wire QP R2 = 30 cm 20 cm 45° 30° 1,-10N .12 = 20 A Solution: i-2.62 10reced out of epe using a 2-axis directed out of the page

Magnetic Field inside a Very Long Solenoid Learning Goal: To apply Ampère's law to find the magnetic field inside an infinite solenoid. In this problem we will apply Ampère's law, written ?B? (r? )?dl? =?0Iencl, to calculate the magnetic field inside a very long solenoid (only a relatively short segment of the solenoid is shown in the pictures). The segment of the solenoid shown in (Figure 1) has length L, diameter D, and n turns per unit length with each...
