Why is the potential of a current carrying loop zero at this position?
[ 1 Answers ]
Yes. I think of it analogous to a spring. It should like someone holding a stretched spring . If I hold the loop with my hands (not allowing it to move), it is like a stretched spring and must have extra stored energy in it. So that energy must be its potential energy. And when I leave it, it...
The relationship between the magnetic field and the solar field
[ 2 Answers ]
What is the relationship between the magnetic field and the area surrounding solar planets? Does the sun is a large magnet, or what that attracts the sun and planets constantly driven? Are the lines that control the path of the planets have a magnetic domain relationship? I'm sorry to frequent...
Finding magnetic field due to a current carrying conductor
[ 0 Answers ]
An infinitely long current carrying conductor is in the shape of the parabola y^2=4x.What is the magnetic field at the point (1,0) if the current flowing is I?
How much current to cancel earth's magnetic field?
[ 1 Answers ]
It can be shown the magnetic field in a long narrow tube is uniform and given by B(Tesla =1.26E-6 N I(amp)? where N is number of wire loops/meter. Assuming the solenoid is aligned along the Earth's magnetic field,how much current is needed to cancel the Earth's field? earth's magnetic field is...
Magnetic field in the solenoid?
[ 0 Answers ]
A long solenoid (n = 1200turns/m, radius = 2.0 cm) has a current of a 0.30 A in its winding.A long wire carrying a current of 20 A is parallel to and 1.0 cmfrom the axis of the solenoid. What is the magnitude of theresulting magnetic field at a point on the axis of thesolenoid? View more questions Search
