D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Electromagnetism
	**Related Topics**: Faraday's Law, Maxwell's Equations, Lorentz Force
	**Prerequisites**: Electric and Magnetic Fields, Forces on Charges
## SOLUTION PATHWAY
**Given Information**:
	Multiple choice question about the properties of electric and magnetic fields.
**Method & Steps**:
	1. Analyze each statement based on the principles of electromagnetism.
	2. Identify the incorrect statement.
## OPTION ANALYSIS
[A] ✓: Changing magnetic fields induce electric fields. This is a fundamental principle of Faraday's law of electromagnetic induction. A time-varying magnetic field creates a circulating electric field.
[B] ✓: Changing electric fields induce magnetic fields. This is another cornerstone of electromagnetism, completing the symmetry with Faraday's law.  This principle is part of Ampere-Maxwell's law, showing that a time-varying electric field creates a magnetic field.
[C] ✓: Electric fields exert forces on stationary charges.  This is the basic definition of how electric fields interact with charges. The force is given by $\vec{F} = q\vec{E}$, where $\vec{F}$ is the force, $q$ is the charge, and $\vec{E}$ is the electric field.
[D] :x: Magnetic fields exert forces on stationary charges. This statement is incorrect. Magnetic fields only exert forces on *moving* charges. The force exerted by a magnetic field on a moving charge is given by the Lorentz force law: $\vec{F} = q(\vec{v} 	imes \vec{B})$, where $\vec{v}$ is the velocity of the charge and $\vec{B}$ is the magnetic field. If $\vec{v} = 0$ (stationary charge), then $\vec{F} = 0$.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the effects of electric and magnetic fields on charges: Remember that electric fields act on both stationary and moving charges, while magnetic fields only act on moving charges.
		2. Misinterpreting Faraday's and Ampere's laws: Ensure a clear understanding of the relationship between changing magnetic fields and induced electric fields, and vice-versa.
	**Quick Tips**:
		1. Right-hand rule: Use the right-hand rule to determine the direction of the magnetic force on a moving charge.
		2. Visualize field lines: Visualizing electric and magnetic field lines can help understand their behavior and effects on charges.
