![### Magnetic Field and Induced EMF in a Square Loop Circuit
**Problem Statement:**
A square loop circuit, as depicted in the figure, exists in a magnetic field given by \(\vec{B}(t) = 4 \hat{z} \cos(2 \pi 10^3 t) \text{ mT}\). Analyze the square loop to address the following questions:
#### (a) What is the total flux \(\Phi\) passing through the loop?
#### (b) What is the induced EMF?
#### (c) What is the current in the loop?
#### (d) Indicate the direction of the current at \(t = \frac{1}{8} \times 10^{-3} \text{s} = 0.125 \text{ms}\) on the figure below with an arrow and briefly justify your answer.
**Figure Description:**
The provided figure shows:
- A square loop with each side measuring 0.5 m.
- The top side of the square loop carries a resistor of 500 \(\Omega\).
- The magnetic field \(\vec{B}\) is oriented normal to the plane of the loop and directed along the z-axis (indicated by the dot inside the circle).
**Graph/Diagram Explanation:**
The diagram presents an \(xy\)-plane with the square loop situated in it. The coordinates specify that the sides of the loop align parallel to the x and y axes. The magnetic field vector \(\vec{B}\) pointing out of the plane is denoted with a circle containing a dot (indicating the tail of the vector perpendicular to the plane). The resistor in the loop emphasizes the circuit component for calculating the current derived from induced EMF.
**Calculation Steps:**
1. **Flux (\(\Phi\)):**
- Calculate the total magnetic flux passing through the loop at any time \(t\).
2. **Induced EMF (ε):**
- Use Faraday’s law of induction to determine the induced EMF in the loop due to the changing magnetic field.
3. **Current (\(I\)):**
- Derive the current using Ohm's law, considering the resistance value in the loop circuit.
4. **Current Direction:**
- At \(t = 0.125 \text{ms}\), determine and indicate the direction of the induced current on the given figure by applying Lenz's](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1345a87f-3d4a-45ee-a13b-cb772771cc65%2F6082dff9-3069-4a4c-b88b-8d7d271be200%2Fj87b3w8_processed.png&w=3840&q=75)
