If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become magnetized by induction through the wire coil. It would temporarily gain magnetic properties while in contact with the coil, but would lose them once removed.
Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
When a direct current passes through a coil of wire, it creates a magnetic field around the coil. This magnetic field induces magnetization in nearby iron, aligning the iron's domains to create a magnetic field in the iron itself. This is known as electromagnetic induction and is the principle behind electromagnets.
What happen when a coil of wire wrap around a bar of iron is a?
When a coil of wire is wrapped around a bar of iron and an electric current is passed through the coil, it creates an electromagnet. The magnetic field produced by the coil around the iron bar enhances the magnetism of the bar, resulting in a stronger magnetic effect than the bar itself would have on its own. This setup is commonly used in devices such as electromagnets, transformers, and electric motors.
Why is the cylindrical core of soft iron used in moving coil galvanometer?
A cylindrical core of soft iron is used in a moving coil galvanometer because soft iron has high magnetic permeability, meaning it enhances the magnetic field produced by the coil. This helps increase the sensitivity and responsiveness of the galvanometer to small currents passing through the coil.
What is a solenoid called when an iron rod is inserted in its center?
When an iron rod is inserted in the center of a solenoid, it is called an electromagnet. The iron core increases the magnetic field strength generated by the solenoid, making it more effective for various applications such as in electric motors or magnetic locks.

What will happen in the absence of iron cylinder in a moving coil galvanometer?
it will not work
Can Cooper be used as a magnet?
When copper is used as a wire to build a coil with a lot of whorls and a piece of iron is inserted in the hole of the coil this is called an electromagnetic device since that a voltage is applied in the coil, thus generating an electromagnetic power which is similar to that natural magnetic iron.

What would happen if you kept hydrochlic acid in iron containers?
The iron would bubble and flammable gas would be released
What would happen if you iron yarn?
it becomes straight
What consists of a coil with an iron core and a movable iron bar?
A coil with an iron core and a movable iron bar constitutes an electromagnet. When an electric current flows through the coil, it generates a magnetic field that attracts the iron bar, causing it to move. This device is commonly used in various applications such as in electric motors and doorbells.
What is the construction and working details of moving iron and moving coil ammeters and moving coil voltmeters?
Different b/w a moving coil instrument and a moving iron instrument
What happens when you plug an iron into an electrical socket?
Enclosed within the iron base is a coil , somewhat like the coil on an eleritic stove . the coil heats the base and water tank on a steam iron . The iron also contains a heat regulator to control ironing temp.
