**Electromagnetic Induction Problem**A flat coil is wrapped with 200 turns of very thin wire on a square frame with sides 18 cm long. A uniform magnetic field is applied perpendicular to the plane of the coil. If the field changes uniformly from 0.50 T to 0.00 T in 8.0 s, find the emf induced in the coil.**Options:**a) 2.1 mV b) 4.1 mV c) 0.21 V d) 0.41 V **Explanation:**This problem involves electromagnetic induction, where a change in magnetic field through the coil induces an electromotive force (emf). The emf can be calculated using Faraday's Law of Induction:\[ \text{emf} = -N \frac{\Delta \Phi}{\Delta t} \]where:- \( N \) is the number of turns in the coil,- \( \Delta \Phi \) is the change in magnetic flux,- \( \Delta t \) is the time over which the change occurs. **Calculation Steps:**1. **Compute the area of the square coil:** - Area \( A = \text{side} \times \text{side} = 0.18 \, \text{m} \times 0.18 \, \text{m} \).2. **Calculate the change in magnetic flux (\( \Delta \Phi \)):** - Initially, \( \Phi_{\text{initial}} = B_{\text{initial}} \times A \). - Finally, \( \Phi_{\text{final}} = B_{\text{final}} \times A \) (where \( B_{\text{final}} = 0 \)). - Hence, \( \Delta \Phi = \Phi_{\text{final}} - \Phi_{\text{initial}} = 0 - (B_{\text{initial}} \times A) \).3. **Substitute the values into Faraday's equation to find the induced emf.**This problem teaches the principles of electromagnetic induction and requires understanding of how changing magnetic fields can induce voltage in a conductive loop.
