What is the number of electrons equal to? The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between […]
Why should foods be refrigerated?
Why should foods be refrigerated? Refrigeration slows bacterial growth. Bacteria exist everywhere in nature. They are in the soil, air, water, and the foods we eat.

Is magnetic field inside a toroid zero?
Is magnetic field inside a toroid zero? The magnetic field lines inside the toroid are concentric circles. The magnetic field is homogeneous inside the toroid and zero outside the toroid. We asses the direction of the magnetic B-field by the right-hand rule. Why is there no magnetic field outside a toroid? After applying Ampere’s Law, […]
