When both positive and Negative charged wire ends touch it. (Try it, it's fun)
to transfer the energy passes from the wire so that the nail able to pick up the paper clips
The wire-wrapped nail was able to pick up the paper clips because the wire acts as a magnet when an electric current flows through it, creating a magnetic field that attracts the paper clips. This is an example of how electromagnetism can be used to manipulate magnetic objects.
A Weakly magnetised nail will pick up less paper clips then a highly magnetised nail, Hope That Helps:)
no it only gives more room to pick up paper clips
The study likely tested how the size of the nail (diameter, length) affects the electromagnet's strength. This could demonstrate how changes in the core material impact magnetic properties. The number of paper clips picked up would increase with a larger or more magnetic core, showing a proportional relationship.
Something either sticky or magnetic might pick up paper clips.
Yes, the shape of a magnet can affect how many paper clips it can pick up. Magnets with a stronger magnetic field and larger surface area can typically pick up more paper clips compared to smaller or weaker magnets. Additionally, the orientation of the magnet in relation to the paper clips can also impact its ability to pick them up efficiently.
An electromagnet is a piece of metal that can be affected by magnetism (usually iron) that is wrapped in a electric conducting thread or wire (usually copper wire.) A really easy way to make an electromagnet yourself is to take a iron nail and wrap it in some copper wire. Then just connect the two ends of the wire and connect it to a AA battery. Test it by using the end of the nail to pick up some paper-clips and such.
The nail is demonstrating induced magnetism. When the magnet comes into contact with the nail, it temporarily magnetizes the nail by aligning the magnetic domains within it, allowing the nail to pick up the paper clip. This effect lasts only as long as the nail remains magnetized, which typically diminishes once the external magnetic field is removed.

Nope. Granite is largely Calcium Carbonate (Ca2CO3). Calcium carbonate is not ferromagnetic and does not produce nor interact with magnetic fields.
Well, honey, any rock with a bit of magnetite in it could pick up those pesky paper clips. Magnetite is a magnetic mineral found in certain types of rocks like lodestone. So, if you're tired of struggling with those paper clips, just grab a rock with a little magnetite and watch them cling like your ex on social media.
