“Earth rotates through the axisymmetric part of its own magnetic field, but a simple proof shows that it is impossible to use this to generate electricity in a conductor rotating with Earth ...

Fleming’s Left Hand Rule can be used to determine the direction of the force, current or magnetic field. This force forms the basis of the electric motor. A current carrying conductor creates ...

He Qinglin’s group at the Center for Quantum Materials Science, School of Physics, has reported the first observation of non-reciprocal Coulomb drag in Chern insulators. This breakthrough opens new ...

electrically insulated conductor via long-range Coulomb interactions. Chern insulators are magnetic topological materials that show a quantized Hall effect without external magnetic fields ...

→ Magnetic field lines never intersect with each other. → Every point on the circular loop will act as a straight conductor. → Magnetic field lines are closer near the conductor which means ...
