A coil of wire containing N turns is in an external magnetic field that is at a LaTeX: 45^o45 o angle from the plane of the coil and is steadily changing. Under these circumstances, an emf V is induced in the coil. If both the rate of change of the magnetic field and the number of turns in the coil are now doubled (but nothing else changes), what will be the induced emf in the coil?

A rectangular coil with N turns and area A is place in a uniform magnetic field directed into y-direction. (a) What amount of emf is induced in the coil if the coil doesn’t move or rotate? . Let’s say the coil rotates about the z-axis through its center at a constant angular velocity LaTeX: \omegaω. (b) What would be total magnetic flux through the coil as a function of LaTeX: \thetaθ ? (LaTeX: \thetaθ is the angle between the directions...

A solenoid (coil) of radius R has 10 turns per centimeter. It is 10cm long, and the coiled wire carries a current I. In addition to the coil of wire, a second wire runs right down the central axis of the solenoid, carrying a current of 2I. (The solenoid wire doesn't intersect this second wire, because the former wraps around the latter, always a distance R away.) A) Find the magnitude of the total magnetic field at a distance R/2...

The magnetic field inside a superconductive magnet is 6T. The length of the coil body is l = 30cm and the diameter d = 2cm. The coil is made of 1km long cable of a superconductive Nb-Ti alloy and is found surrounded by liquid Helium (T=4.2K) and therefore in the superconductive phase. a) Determine the number of windings b) Determine the current in the coil c) Determine the electrical Power required c

A circular coil (830 turns, radius = 0.087 m) is rotating in a uniform magnetic field....

A circular coil (830 turns, radius = 0.087 m) is rotating in a uniform magnetic field. At t = 0 s, the normal to the coil is perpendicular to the magnetic field. At t = 0.021 s, the normal makes an angle of 45o with the field because the coil has made one-eighth of a revolution. An average emf of magnitude 0.075 V is induced in the coil. Find the magnitude of the magnetic field at the location of the...

A square coil of thin wire with 4 turns and side-length 3 cm sits inside an ideal solenoid. The axis of the solenoid is along +k, but the axis of the coil is tilted at a fixed unknown angle θ from the +z-axis. The solenoid has n = 5000 turns/meter, and carries current I(t) = 5t3– 4t2+ t + 5 [units of Amperes with t given in seconds] counterclockwise. The wire of the coil has cross-sectional area A = 50 μm2, and the...

A coil is wrapped with 291 turns of wire on the perimeter of a square frame of sides 25.3 cm. Each turn has the same area, equal to that of the frame, and the total resistance of the coil is 2.05 Ohm. A uniform magnetic field is turned on perpendicular to the plane of the coil. If the field changes linearly from 0 to -0.0491 Wb/m2 in a time of 1.07 s, find the magnitude of the induced emf in...

What is the magnitude of the magnetic field B at the centre of the coil?

A circular coil of wire consisting of 100 turns, each of radius 8.0 cm carries a current of 0.40 A. What is the magnitude of the magnetic field B at the centre of the coil?

A flat coil of wire is placed in a uniform magnetic field that is in the y direction. (i) The magnetic flux through the coil is maximum if the coil is (a) in the xy plane(b) in either the xy or the yz plane (c) in the xz plane (d) in any orientation, because it is constant. (ii) For what orientation is the flux zero? Choose from the same possibilities.
