yes it contains magnet
No, a magnet will not attract a wood ruler. Wood is a non-magnetic material, meaning it does not contain ferromagnetic substances that would respond to a magnet's magnetic field. Therefore, there will be no attraction between the magnet and the wood ruler.
Most CD players use electromagnetic switches called relays. Have you ever turned on the power on your CD player or another appliance, and heard a click immediately before it went on? That's a relay doing its job. In a relay, a small current runs through a coil which is right next to a switch with a magnet in it. The coil pulls on the switch, closing it and turning on the device. Relays are useful because they use a small current to control a much larger one. As a result, they are often used in the power supplies of electronic devices such as CD Players
Materials that are attracted to a magnet are those that contain iron, nickel, or cobalt. These materials have unpaired electrons that align in the presence of a magnetic field, creating a magnetization that is attracted to the magnet.
No, a magnet does not attract a dime. Dimes are made primarily of a copper-nickel alloy, which is not magnetic. Only materials that contain ferromagnetic metals, like iron, cobalt, or nickel, will be attracted to a magnet.
No, a torch does not typically contain a magnet. The main components of a torch are a battery, light bulb or LED, and a casing to hold everything together.

Yes, some electric can openers contain a magnet to keep the lid from falling to the counter when the can opener cuts if off.
Objects that contain iron, nickel, or cobalt are attracted to a magnet.
No they don't.
No, yeast is not attracted to a magnet as yeast does not contain any metallic material
You can attract objects that contain iron by using a magnet, as iron is a magnetic material. When you bring a magnet near objects containing iron, the magnetic force will cause them to be attracted to the magnet.
It should contain music
A CD can contain 99 tracks
A CD is a way to store data. So if a virus has been written on the CD, then it can.
Iron and other magnetic minerals are some of the most common elements on the planet. Soil and oil that contain these will leave a residue of them behind on a magnet.
