How do dryers use magnetism?
The magnetic hold in coil uses magnetism along with the electric motor that turns the drum.
What role to polarity and action potential play in sending out nervous signals?
Polarity refers to the difference in charge across a neuron's membrane, which is essential for generating an action potential. When a neuron is stimulated, depolarization occurs, leading to a rapid influx of sodium ions and a transient reversal of polarity. This action potential propagates along the axon, allowing the transmission of electrical signals. Ultimately, the action potential triggers neurotransmitter release at the synapse, facilitating communication between neurons.
What branch of science studies heat and magnetism?
Physics is the branch of science that studies heat and magnetism, along with other fundamental forces and interactions in the universe. This includes fields such as thermodynamics for heat and electromagnetism for magnetism.
Why is a solid moved along by a gas?
This is due to capillary action and the rules of solubility and polarity.
How is the world a magnet?
The magnet is in the world because magnetism is one of the fundamental forces of the universe, along with gravity.
How do rocks along the central valley of the mid ocean ridge provide evidence for sea floor spreading?
because the scientists found that the farther the rocks the older the rocks were. so the youngest rocks were found near the mid-ocean ridge. this showed that sea-floor spreading took place. +++ The primary evidence is "magnetic striping": remnant magnetising by the Earth's magnetic field of the iron compounds in the basalt forming the ocean floor. The magnetic traces are parallel to the spreading-ridges, and their polarity reflect the field's periodic reversal. The further from the ridge, the older the stripes. The rock is imprinted with the magnetism as it cools below a certain point in being eruped along the ridge.
Does steel retain magnetism better than iron?
Yes, steel retains magnetism better than iron because it is an alloy that contains iron along with other elements like carbon. The addition of other elements in steel helps to stabilize and strengthen the magnetic properties, making it more effective at retaining magnetism compared to pure iron.
What happened to the iron filings magnetism after several shakes?
After several shakes, the iron filings lose their organized alignment with the magnetic field of the magnet. Initially, they align along the magnetic lines of force, demonstrating their magnetism. However, the shaking disrupts this order, causing the filings to scatter and lose their magnetic orientation. As a result, they may no longer visibly demonstrate magnetism unless re-aligned by the magnetic field.
What is the polarity of Aloe Vera gel?
aloe vera is very good for your hair has less alcohol than any other gel
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
Electricity is one of two aspects of which fundamental force?
The force that includes both electricity and magnetism is called the electromagnetic force.
When new basalt forms along mid-ocean ridges it become magnetized?
accorsing to the earths magnetic field
