The force acting on an electrically charged particle in a magnetic field depends on the magnitude of the charge, the velocity of the particle, and the strength of the magnetic field. The Lorentz force has the peculiar property that it causes particles to move in right angles to their original...
What magnetic force does the wire experience? View Solution Knowledge Check A conducting circular loop of radius r carries a constant i. It is placed in a uniform magnetic field B such that B is perpendiclar to the plane of thre loop is .What is the magnetic force acting on the loop?
An electromagnet and permanent magnet wouldn't adversely affect SD cards and flash drives. These products don't depend on magnetic fields and forces as much as they would need to for magnets to damage them. Other technology such as cables can be affected if they aren't appropriately protected ...
Does friction depend on area under contact force? The applied force of a 2.0-kg object is 8.4 N and the friction is 2.2 N . What is the motion of the object? Is friction an electromagnetic force? Mathematically, how does static friction depend on the normal force? What kind of function...

Why does the moon have phases? The phases of the moon are a consequence of its motion around Earth in relation to the geometry assumed with respect to the sun. To better understand how it works, let us, first of all, remember that the moon does not emit its own light but reflects tha...
It takes advantage of two unique properties of high-temperature superconductors: the "Meissner effect" which allows a superconductor to completely repel the magnetic fields around it to achieve levitation, and "flux pinning," which keeps the superconductor steady above its ma...
