1. Accurately apply the left-hand rule to determine the direction of Ampere force and Lorentz force, and understand the special case of force direction for negative charges.
2. Master the formula for calculating the magnitude of Lorentz force, and independently derive the formulas for radius and period of circular motion of charged particles in a uniform magnetic field.
3. Analyze and explain the working principles of mass spectrometers, cyclotrons, velocity selectors, and magnetohydrodynamic generators.
4. Accurately state the content of Lenz’s Law and Faraday’s Law of Electromagnetic Induction, and use the right-hand rule to determine the direction of induced current when cutting magnetic field lines.
5. Flexibly apply the formulas E = n \frac{\Delta \Phi}{\Delta t} and E = Blv \sin \theta to calculate induced electromotive force in various physical scenarios.
6. Analyze complex electromagnetic phenomena such as self-inductance, eddy currents, and electromagnetic damping from the perspective of energy conversion, and solve related practical physics problems.
7. Analyze the process by which a coil rotating in a magnetic field generates alternating current, skillfully write instantaneous value expressions, and perform conversions between peak and root mean square (RMS) values.
8. Understand the basic principles of ideal transformers, and use the proportional relationship between voltage and number of turns to solve circuit problems.
9. Comprehend the mechanism of power loss in long-distance power transmission, calculate voltage drop and power loss in transmission lines, and explain the economic advantages of high-voltage transmission.
10. Describe the periodic changes in charge, current, electric field energy, and magnetic field energy in an LC oscillating circuit.
