The magnetic field due to the current element can also be written as, d B = 4 π ε 0 c 2 1 r 3 i d l × r where, c = μ 0 ε 0 1 = speed of light in vacuum. MediumFind the magnetic field at {eq}P {/eq} produced by this current element. Biot-Savart Law: According to Biot-Savart law, the magnetic field produced by the small current element at a point is given byThe magnetic field is related to the current as follows. Assume that dl is an element of length (pointing in the direction of current flow) of a filamentary wire that carries a current I and r is the coordinate vector from the element of length to an observation point P, as shown in Fig. 5.4. Then the magnetic field dB at the point P is givenFind the magnetic field at P produced by this current element, dBx, dBy, dBz. Show transcribed image text A short current element dl = (0.500 mm) j-hat carries a current of 9.20A in the same direction as dl. Point P is located at r-vector = (-0.730m) i-hat + (0.390m) k-hat.

A short current element dl =(0.500mm)j^ carries a current

Magnetic Field Produced by a Current-Carrying Solenoid. A solenoid is a long coil of wire (with many turns or loops, as opposed to a flat loop). Because of its shape, the field inside a solenoid can be very uniform, and also very strong. The field just outside the coils is nearly zero. Figure $\PageIndex{3}$ shows how the field looks and howThe total magnetic field caused by several moving charges is the v fields caused by the Individual charges. We can use this principle with Section 29-2 to find the magnetic field produced by a current in a we begin by calculating the magnetic field caused by a short current carrying conductor, as shown in Fig. 29-3a.1. Make a drawing and use RHR-2 to find the direction of the magnetic field of a current loop in a motor (such as in Figure 1 from Torque on a Current Loop). Then show that the direction of the torque on the loop is the same as produced by like poles repelling and unlike poles attracting.The magnetic field intensity dH produced at a point P by the differential current element Idl is proportional to the product of Idl and the sine of the angle α between the element and the line joining P to the element and is inversely proportional to Idl sin α the square of the distance R between P and the element.Figure 9.1.2 Magnetic field of a current element. Example 9.1: Magnetic Field due to a Finite Straight Wire A thin, straight wire carrying a current I is placed along the x-axis, as shown in Figure 9.1.3. Evaluate the magnetic field at point P. Note that we have assumed that the leads to the ends of the wire make canceling contributions to the
