motional emf i think... change in area and magnetic field
Homework Statement
A rectangular loop is located in a uniform magnetic field of magnitude 0.29 T directed perpendicular to the plane of the coil. If the area of the coil increases at the rate of 5.2 10-3 m2/s, what is the magnitude...
Homework Statement
A square, single-turn wire loop 1.00 cm on a side is placed inside a solenoid that has a circular cross section of radius 3.00 cm, as shown in the figure below. The solenoid is 16.0 cm long and wound with 95 turns of wire.
(a) If the current in the solenoid is 3.00 A...
Homework Statement
An infinitely long conductor carrying a current I in the positive z-direction lies on the z-axis.
A conducting triangle of wires lies in the yz-plane, which moves with a speed v in the positive y-direction.
The following figure shows the situation on time t = 0:

im thinking of the classic airplane problem. the one where the flying airplane develops a voltage across its wingspan. now this was posed to me as a motional emf problem and i bought it then but simultaneously thought that it seemed like a hall effect problem.
so two questions
now that i think...
Hey lads, if anyone can, please check If I am correct... Thanks :)
[i]A 100 turn circular coil has a diameter of 2 cm and a resistance of 50 Ohms. The plane of the coil is perpendicular to a uniform magnetic field of magnitude 1 T. The direction of the field is suddenly reversed.
(a) Find...
" A circular loop of wire 10 cm in diameter is placed with its normal making an angle of 30 degrees with the direction of a uniform 0.50T magnetic field. The loop is "wobbled" so that its normal rotates in a cone about the field direction at the constant rate of 100rev/min; the angle between the...
if someone could help me with understanding the basics of Lenz's law and Motional emf i'd really appreciate it. I'm having some trouble applying it to questions that were assigned.
I have a variation of the Motional EMF in Tiplers Physics Second Edition 28-1. A conducting rod of mass m and length l sliding along conducting rails connected by a resistor with a uniform magnetic field normal to the movement of the rod. The variation is that instead of just a resistor, the...
