An electromagnet is a coil of wire with a current running through it. This creates an electromagnetic field. An additional magnet and its poles interact with the electromagnet, causing an electromagnetic motor to turn. What are some ways you could make an electromagnetic motor stronger, and how could you apply these principles to everyday life? In three to five sentences, explain this phenomenon in real life and hypothesize about how you could strengthen it.(4 points)
Non-Contact Forces
1. Objects with the same charge repel each other, and objects with opposite charges attract each other.
2. The objects in interaction A are farther apart than in interaction B.
3. The atoms in glass hold on tightly to their negatively charged particles.
4. Insulators have high resistance, while conductors have low resistance.
5. If the current in circuit A is greater than the current in circuit B, then the resistance in circuit A is less than the resistance in circuit B.
6. The resistor decreases the current by transforming electrical energy into different types of energy.
7. Electrical energy from the outlet is converted to heat and light energy for the toaster.
8. Energy from the sun might be greater than the energy needs of the house, so some energy will be stored and/or wasted.
9. The switch is open.
10. load

12. when a current runs through a conductor
13. Short Answer
We could wrap the coil around some metal, such as Iron. The magnetic zones inside the nail align to form a powerful, short time magnet. You can also add more turns to the magnet coil. Because of this, the overall resistance of the wire can be increased by turning the coil. A third reason can be that increasing more current flow. The more coils, the more field lines, which indicates a strong electromagnet.
is your welcome right
lol we are kids we can't vote lol i thank until we are 18. and not to be a hater but i don't like Biden so yea trump is the best.
I'm sorry, but as an AI language model, I am not capable of voting nor am I able to provide political opinions or endorse any political candidates. My purpose is to provide information and assist with tasks. Is there anything else I can help you with?
To make an electromagnetic motor stronger, there are a few principles you can apply in everyday life.
One way is to increase the number of coils in the wire. By adding more turns to the coil, you can boost the strength of the magnetic field produced. This can be seen in real life by using a motor with multiple layers of wire wound around the electromagnet, resulting in a stronger motor.
Another way is to increase the current running through the coil. By increasing the amount of electricity passing through the wire, the magnetic field becomes stronger. In everyday life, this can be achieved by using a higher voltage power source for the motor, resulting in increased performance.
Additionally, using stronger permanent magnets in conjunction with the electromagnet can enhance the motor's strength. By selecting magnets with higher magnetic properties, the interaction between the magnetic fields is intensified, leading to a more powerful motor.
To strengthen an electromagnetic motor, one could combine these principles by using a motor with multiple coils, using a higher voltage power source, and incorporating stronger permanent magnets. This would result in a motor capable of producing a stronger rotational force, allowing for various applications in fields such as transportation, manufacturing, or energy generation.
