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...

Calculate the magnitude of the magnetic field from a circular loop of wire of radius 0.20 m, carrying a current of 2.4 A, and with 300 turns of wire at a distance of 2.0 m away from the loop along the axis of the loop.
Find the magnetic field: a. at the center of a 12-turns circular coil of radius 5.00 cm that carries a current of 4.00 A. (6.03 x 10-4 T) b. at the center of a 600-turns solenoid of length 20.0 cm, radius 1.40 cm that carries a current of 4.00 A (0.015T). c. at the center of a square current loop of side 50 cm that carries a current of 1.5 A (3.4µT). d. due to current-carrying wires of different geometries
A thin coil has 60 circular turns of wire of radius 4 cm. The current in the wire is 8 amperes. (a) What is the magnetic dipole moment of this coil? (b) At a distance of 40 cm from the center of the coil, along the axis of the coil, what is the approximate magnitude of the magnetic field contributed by the coil? The coil is placed with its axis along the x axis. A bar magnet whose magnetic dipole...
A current-carrying wire moves toward a coil A long straight wire carrying current I is moving with speed v toward a small circular coil of radius r containing N turns, which is attached to a voltmeter as shown. The long wire is in the plane of the coil. (Only a small portion of the wire is shown in the diagram.) Voltmeter N turns radius r The radius of the coil is 0.02 m, and the coil has 11 turns. At...
What is the ratio of the magnetic field at the center of a single loop of wire of radius R to that at a point P located at a distance R away from a very long current-carrying wire?
Derive an expression for the magnetic field produced at point P due to the current-carrying wire shown in the figure below. The curved parts of the wire are pieces of concentric circles. Point P is at their center. (Use the following as necessary: 1, R1, R2, θ, and O. Assume that the +x axis is to the right, the +y axis is up along the page, and the +z axis is out of the page.) μο Need Help?Read It
Two circular coils of current-carrying wire have the same magnetic moment. The first coil has a radius of 0.092 m, has 144 turns, and carries a current of 4.5 A. The second coil has 166 turns and carries a current of 9.3 A. What is the radius of the second coil?
