For many technical applications, it is desirable to have a uniform magnetic field, i.e. a field...
7 Ideal Solenoid - prediction To find out whether the Slinky is a good realization of an ideal solenoid, we will explore the magnetic field in the Slinky qualitatively. For each of the following regions, predict the results of the net magnetic field compared to the value B1 (near the center of the loop, in the middle of the Slinky). Decide whether the value should be the same, larger, smaller or zero. B. B6 COOOO000 B. B2 B3 BA Hypothesis...
If have a loop of wire with one turn, and a current Iflowing through it then the magnetic field at the center of thecoil is given by:B=μ0I/2r,where μ0=1.2566x10-6N/A2 and r is the radius of the loop. When youhave N loops to form a coil, the magneticfield is justmultiplied by N:B=Nμ0I/2r.MAGNETIC FIELD OF A SOLENOID: If a coil is strected out toform a tube, then you have a solenoid. The magnetic field of asolenoid far from the ends is givenbyB=μ0In,where n...

Assume the current runs clockwise (looking down on thecoil).a) At the geometric center of the cavity inside the solenoid: the magnetic fieldpoints away from you, into the pagepoints toward you, out of the pagepoints upwardpoints downwardpoints to the rightis approximately zeropoints to the left
4) With FlipltPhysics you have already found the field due to a circular loop of radius R carrying current I at a point a distance x from the center of the loop but along the axis. A pair of such loops placed a distance R apart makes up a Helmholtz coil. Such a coil is used in the e/m ratio lab (a) Determine the magnetic field as a function of x along the axis of a Helmholtz coil, with x...

III. Extension to calculating the magnetic field on the axis of a solenoid . y! R A solenoid has a length of Land is comprised of N coaxial loops with radius R. All of the loops are connected so that they all carry the same current in the same direction. You want to determine the field at a point on the y axis. In the previous example you calculated the magnetic field ^ due to one loop. This is an...
