Where is a magnetic field the weakest?
Where is a magnetic field the weakest? equator What makes a magnet stronger or weaker? Most substances have an equal number of electrons spinning in opposite directions, which cancels out their magnetism. These substances have high magnetic permeability and make the strongest magnets. Iron, cobalt and nickel are among these substances. Neodymium iron boron (NdFeb) […]
When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer?
When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer? Answer Expert Verified During charging and discharging of the capacitor, there is a flow of charge from the battery towards the plates of the capacitor, which produces a conduction current in the circuit.

Why force is directly proportional to pressure?
Why force is directly proportional to pressure? From equation (1) it is evident that as force increases, pressure also increases and as force decreases pressure also decreases since force is in the numerator. Or pressure is directly proportional to the applied force. Whereas as the area increases, the pressure decreases. i.e. it increases with the […]
