The main task of this video either listening and focusing on boosting new vocabulary or improving the knowledge of collocations.

How does the right hand rule help us determine the direction of the magnetic field around a wire? Can you demonstrate this rule with an example?

Explain the difference in magnetic field patterns between a single wire carrying current and a coil of wire (solenoid). How does the arrangement of the wire affect the strength and uniformity of the magnetic field?

Discuss the advantages of using an iron core within a solenoid to enhance its magnetic field strength. Why does the iron core amplify the magnetic field, and what are the consequences of its magnetization when the current is turned off?

What are some real-world applications of electromagnets? How do engineers utilize the ability to control and manipulate magnetic fields in these applications?

In what ways can we increase the strength of an electromagnet? Consider factors such as increasing current, adding more turns to the coil, and altering the properties of the core material. How do these adjustments affect the performance of the electromagnet in practical scenarios?
