Explanation:
Production of Magnetic Field:
- When electricity is passed through a coil, a magnetic field is produced around the coil. This is due to the flow of electric current which creates a magnetic field according to Ampere's law.
Development of Heat in the Coil:
- As electricity passes through the coil, resistance in the coil causes the development of heat. This is because the resistance in the coil converts some of the electrical energy into heat energy.
Loss of Energy in the Form of Heat:
- Energy is lost in the form of heat due to the resistance in the coil. This loss of energy is known as Joule heating, where some of the electrical energy is converted into heat energy and is dissipated.
Conclusion:
- In summary, when electricity is passed through a coil, a magnetic field is produced around the coil, heat is developed in the coil due to resistance, and energy is lost in the form of heat. These phenomena are important in understanding the behavior of coils in electrical circuits and devices.
