### Understanding the Magnetic Field in a Toroidal SolenoidThe question explores the characteristics of the magnetic field within a tightly-wound toroidal solenoid. Below are the options provided:- **Option 1: Varies as the square of the current**- **Option 2: Is uniform**- **Option 3: Is always zero**- **Option 4: Is non-uniform**### Explanation:A toroidal solenoid is a coil shaped like a donut, wound tightly, with wire loops forming a continuous path. The magnetic field inside a toroidal solenoid is significant for the following reasons:- **Uniform Magnetic Field**: The magnetic field inside a toroidal solenoid is uniform and contained within the core of the solenoid. This is because the circular symmetry and closed-loop structure cancel out any external magnetic fields. - **Dependence on Current**: The strength of the magnetic field is directly proportional to the current flowing through the wire and the number of turns per unit length. However, it doesn't vary as the square of the current.- **Zero Outside**: Outside the solenoid, the magnetic field is effectively zero due to the closed-loop configuration.#### Correct Answer:The magnetic field inside a tightly-wound toroidal solenoid is uniform.

Concept explainers

Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.

A very long solenoid having a square cross section 5.0 cm on a side is connected to a power supply that drives enough current through the solenoid to create a 0.20-T magnetic field in its interior. Imagine that we surround this solenoid with a circular loop 10 cm in diameter whose resistance is 0.015 Ω and which is oriented with its face perpendicular to the solenoid’s axis. Suppose that when we switch off the power supply, it takes 30 ms for the current flowing through the solenoid to drop to zero. About how much current flows in the loop during this time?
