**Chapter 18 - PHYS 203: Fundamentals of Physics** # Magnetism ## Key Concepts: - **Magnetic fields** - **Current induction of magnetism** - **Ampere’s Rule:** \(\left| \vec{B} \right| = \frac{{\mu_0 I}}{{2\pi R}}\) ## Reinforcement: 1. **Problem 1:** What would be the magnitude of an induced magnetic field from a transmission line 3.3 m above the point of measurement if the current it carries is 783 A? 2. **Problem 2:** A mechanic wants to use a solenoid she found on a car starter. If the solenoid is 0.124 m long and has 845 turns of wire, what current is required to produce a magnetic field of \(1.83 \times 10^{-4} \, \text{T}?\) 3. **Problem 3:** Find the current in a wire with a magnetic field defined by: \(B = 4.29 \times 10^{-5} \, \text{T}, \, R = 1.4 \, \text{m}\) 4. **Problem 4:** If a surveyor is 10.5 m below a west-to-east running transmission line carrying 843 A, what would be the error in the angular measurement if the Earth's magnetic field is found to be \(\vec{B} = 3.3 \times 10^{-4} \, \text{T}_{\text{east}} + 2.45 \times 10^{-4} \, \text{T}_{\text{north}}?\)
