Magnets are items that have the ability to alter the objects around them. The magnetic field is the space or region that is affected by the magnetic force around a magnet. Magnets are typically hard objects, however some are relatively soft.
A magnet is defined as an object that has the ability to attract other objects. In fact, the magnetic field has the ability to attract as well as repel items. Children may learn about magnets and magnetic fields by using plastic straws in this simple experiment.
Tools and Materials of Simple Experiments; Plastic Straw Magnets
- 2 plastic straws
- 1 bottle of used mineral water complete with a lid.
Step of Simple Experiments; Plastic Straw Magnets
- Prepare tools and materials. Place the bottle with the lid upright.
- Rub the surface of the plastic straw with your hands until it feels warm.
3. Place one straw across the top of the bottle.
4. Hold another straw, bring it close to the straw in the bottle but don’t touch it.
5. Even if there is no wind or other movement, the straw situated across the top of the bottle will move away from the straw in your hand.
Explanation of Step from Simple Experiments; Plastic Straw Magnets
This occurrence shows that a magnetic field exists between the plastic straws. This magnetic field, however, acts as a repulsive force, causing the straw to move away from the other straws.
Naturally occurring magnets are permanent. While artificial magnetic fields are usually temporary. How to create a magnetic field by giving an electric charge to an object is usually done in three ways, namely:
- Rubbing things
This approach is used on plastic straws that have been rubbed to become electrically charged and magnetically charged. Plastic straws repel because the charge is the same.
- Electric Induction
This method usually involves holding a strong natural magnet close to a metal object for a few moments but not touching it. It has been induced by a magnet if a metal object is brought close to another metal and attracts the other metal.
- Conduction of electric current
The trick is to transfer an electric charge from one object to another by touching it.
Isn’t it an interesting experiment this time? Let’s attempt creating a magnetic field with another experiment. It’s even better if you use materials that are both safe and readily available.
