Electric current can be used to create magnets. This phenomenon is known as electromagnetism, where an electric current flowing through a wire generates a magnetic field around it.
When the wire is coiled and current flows through, it enhances the magnetic effect, allowing the wire to function as an electromagnet.
In this expression, q represents the total charge, n is the number of electrons, and e is the magnitude of charge of a single electron (approximately 1.6×10−19 coulombs)
In a hollow body, electric charges distribute themselves uniformly on the outer surface, achieving stability. Inside the hollow body, the electric field is zero, ensuring that the charge remains stable.
Benjamin Franklin He is credited with inventing the lightning conductor in the 18th century as a means to protect buildings from lightning strikes.
Direct Current (DC) refers to the flow of electric charge in a single direction, whereas Alternating Current (AC) periodically reverses direction.
Electric conductors, such as silver, copper, and aluminum, allow electric current to flow easily due to their atomic structure, which facilitates the movement of free electrons within the material.
