Question

A wire and a 10-Ω resistor are used to form a circuit in the shape of a square with dimensions 20 cm by 20 cm. A magnetic field is directed into the plane (into the page) of the circuit. The magnitude of the magnetic field is steadily decreased from 2.70 T to 0.40 T in a time interval of 75 ms.

(a) Draw the figure

(b) What is the direction of the induced current through the resistor? Reasons must be stated step by step. 
 
(c) What is the magnitude of the induced current?
### Explanation of the Circuit Diagram

This image presents a simple electrical circuit diagram. The diagram features the following key components and metrics:

1. **Dimensions**: 
   - The circuit is laid out within a rectangle measuring 20 cm by 20 cm.

2. **Circuit Components**:
   - A resistor is included in the circuit between points labeled 'a' and 'b'. The resistor has a resistance value of 10 ohms (Ω).
   - The symbols within the rectangle consisting of multiple crosses depict a uniform magnetic field that is perpendicular to the plane of the circuit and into the page.

3. **Layout**:
   - The component layout shows that the resistor is placed horizontally at the lower segment of the rectangle-based circuit border, connecting the two points 'a' and 'b'.

4. **Orientation**:
   - The arrows at the sides of the rectangle denote the dimension measurements, indicating parallel dimensions of the rectangle.

This diagram is representative of a basic electrical circuit setup, integrating a resistor with a specific resistance value and positioned within a magnetic field, indicated by the crosses. This setup is often used to study the interaction of magnetic fields with electric currents and components.
