because it is easy to convey from small bar magnet
The small bar magnet has a stronger magnetic field, at least at short distances.
The bar that affects the compass is the magnet, The bar that is attracted to the magnet is iron, and the bar that is not attracted to the magnet is aluminum.
You can differentiate between a bar of iron and a bar of copper by testing their magnetic properties - iron is attracted to magnets, while copper is not. A bar magnet will attract small iron objects, while a bar of copper will not be attracted.
A compass interacts with a bar magnet by aligning itself with the Earth's magnetic field. The needle in the compass is a small bar magnet that points towards the Earth's magnetic north pole. This alignment allows the compass to determine direction based on the north-south orientation of the magnet.
They are bar magnet ,horse shoe magnet ,lime stone magnet.
The number of paperclips a bar magnet can pick up will depend on the strength of the magnet and the size of the paperclips. In general, a typical bar magnet can pick up several small paperclips at once.
To attract the south pole of a bar magnet, you would need to place it near the north pole of another magnet or in close proximity to the bar magnet's north pole. Since opposite poles attract, positioning the south pole of the bar magnet toward the north pole of the magnet shown will result in a pull toward the magnet. This attraction occurs because magnetic fields interact in such a way that opposite poles draw closer together.
no
Move towards the U magnet so that the poles attach.
If a bar magnet is broken in half, each piece will become its own smaller magnet with its own north and south poles. The strength of each magnet will be weaker compared to the original bar magnet. The overall magnetic field will be distributed between the two smaller magnets.
The magnet bar is used for stirring solutions.
a electromagnet is bigger than a bar magnet
