ok now the last part of the question there are 5 options i eliminated two of them

qn)which of the following is true?

1)the magnitude of the emf is maximum only when the force is zero

2)the magnitude of the force is zero only when the magnitude of the force is maximum.

3)none of the above

which one is it both seem to be correct

<h2>1. What is a magnet in a coiled wire loop?</h2><p>A magnet in a coiled wire loop, also known as a solenoid, is a device that consists of a wire wrapped around a cylindrical core, typically made of iron or another magnetic material. When an electric current is passed through the wire, it creates a magnetic field that can attract or repel other magnets.</p><h2>2. How does a magnet in a coiled wire loop work?</h2><p>A magnet in a coiled wire loop works by using the right-hand rule, which states that if you point your right thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field. As the electric current passes through the wire, it creates a magnetic field that is strongest inside the coil. This magnetic field can be used to attract or repel other magnets, or to convert electrical energy into mechanical energy.</p><h2>3. What are the applications of a magnet in a coiled wire loop?</h2><p>A magnet in a coiled wire loop has many practical applications. It is commonly used in electromagnets, which are used in motors, generators, speakers, and other devices that require a strong magnetic field. It is also used in magnetic sensors, such as in metal detectors and MRI machines, and in particle accelerators to control the path of charged particles.</p><h2>4. How is a magnet in a coiled wire loop different from a regular magnet?</h2><p>A magnet in a coiled wire loop is different from a regular magnet because it can be turned on and off by controlling the flow of electric current through the wire. Regular magnets, also known as permanent magnets, have a fixed magnetic field that cannot be changed. Additionally, the magnetic field of a solenoid is stronger and more concentrated than that of a regular magnet.</p><h2>5. Can the strength of a magnet in a coiled wire loop be changed?</h2><p>Yes, the strength of a magnet in a coiled wire loop can be changed by adjusting the amount of electric current flowing through the wire. The more current that flows through the wire, the stronger the magnetic field will be. Additionally, the number of turns in the coil and the material of the core can also affect the strength of the magnet. </p>
