An electromagnet is not able to move objects made of non-magnetic materials, such as plastic or wood. Additionally, if the object is too heavy or the magnet is not powerful enough, it may not be able to move the object.
Yes, an electric current can move through an electromagnet. When electricity flows through the coil of wire in an electromagnet, a magnetic field is created. This magnetic field can then influence nearby objects or align with other magnetic fields.
When a compass gets near an electromagnet, the magnetic field produced by the electromagnet interferes with the Earth's magnetic field, causing the compass needle to align with the electromagnet's field instead. This phenomenon is known as magnetic deflection.
A compass needle is a tiny magnet that aligns with the magnetic field around it. When brought near an electromagnet, the magnetic field produced by the electromagnet affects the compass needle, causing it to align with the new magnetic field created by the electromagnet.
No, the strength of a magnetic field does not increase as you move away from the electromagnet. The strength of a magnetic field decreases with distance from the source, following the inverse square law. This means that the magnetic field weakens as you move further away from the electromagnet.
True. An electromagnet is used in a galvanometer to create a magnetic field that interacts with the current-carrying coil and causes the needle to move.

Electromagnet is the magnet which is becoming active so long current through the coil flows. If current stops then the magnetism disappears. If a core made up of soft iron is used then magnetism will become more intense but the magnetism exists so long the current flows. Any way electromagnet will behave just like a permanent bar magnet. So electromagnet would set itself along the earth's magnetic meridian.
True. An electromagnet is used in a galvanometer to create a magnetic field that interacts with the current-carrying coil and causes the needle to move.
When you put a natural magnet near an electromagnet, the two magnets can either attract or repel each other, depending on their polarity. This interaction can cause the natural magnet to move or align itself with the electromagnet, demonstrating the magnetic forces at play.
The strength of an electromagnet is not directly related to the speed of the coils. The strength of an electromagnet depends on factors such as the number of coils, the amount of current flowing through the coils, and the type of core material used. Moving the coils faster or slower may impact efficiency or performance in specific applications, but it does not inherently make the electromagnet stronger or weaker.
To use an electromagnet to move a slide latch in a lock, you would first attach the electromagnet to a mechanism that can physically engage the latch. When the electromagnet is activated by applying an electric current, it generates a magnetic field that attracts a ferromagnetic armature or plate linked to the latch. This action would pull the latch away from its locked position, allowing the lock to open. Once the current is turned off, a spring mechanism could return the latch to its original position, securing the lock again.
