The current created by the changing magnetic force also creates an opposing EMF to the magnetic which created the current.MrLobster said:I was watching an experiment that I don't understand. The professor turned a hand crank that generated electricity to light up a bulb. There was also a switch to turn the bulb on and off. When the bulb was on the crank became harder to turn. I don't really understand why that is. Did it somehow create a magnetic force that opposed the motion of the crank?
Mechanical energy is the energy possessed by an object due to its motion or position. It can be in the form of kinetic energy (energy of motion) or potential energy (energy of position).
Electrical energy is the energy carried by electric current. It is the flow of electrons through a conductive material, such as a wire.
Mechanical energy can be converted to electrical energy through the use of a generator. This device converts mechanical energy, usually in the form of rotational motion, into electrical energy by the principle of electromagnetic induction.
Some common examples of converting mechanical to electrical energy include wind turbines, hydroelectric power plants, and bicycles with dynamos that generate electricity while pedaling.
Converting mechanical to electrical energy has a wide range of applications, including powering homes and businesses, transportation, and manufacturing processes. It also plays a crucial role in renewable energy production, as it allows us to harness the power of natural resources such as wind, water, and solar energy.
