The energy stored in a magnetic field is given by ____________ where L...
Explanation:
Magnetic Energy Formula:
- The energy stored in a magnetic field is given by the formula: 1/2 Li^2, where L is the self-inductance of the circuit.
Understanding the Formula:
- The term "1/2" in the formula represents the factor of 1/2 that is commonly used in energy storage calculations.
- The term "Li^2" represents the energy stored in the magnetic field, where L is the self-inductance of the circuit and i is the current flowing through the circuit.
Importance of Self-Inductance:
- Self-inductance (L) is a measure of the ability of a circuit to store energy in its magnetic field when current flows through it.
- The greater the self-inductance of a circuit, the more energy it can store in its magnetic field.
Conclusion:
- Therefore, the correct formula for calculating the energy stored in a magnetic field is 1/2 Li^2, where L is the self-inductance of the circuit.
