Because the molecules in gasoline are inherently non-polar, it takes an extremely strong magnet to cause any polar effect on them. Even the electromagnets used on cranes to pick up junk cars and move them around in junk yards are not strong enough to change the polarity of gasoline noticeably. Any magnet strong enough to induce a noticeable polarity in the molecules in the gasoline would have a catastrophic effect on the metal moving parts of the engines it is burned in and as soon as the gasoline was removed from the magnetic field of the magnets it would revert to its normal non-polar state. Magnets cannot induce any permanent change in the polarity of gasoline.
As a caveat - a little bit of polar materials are often added to gasoline to aid in complete combustion and to impart some engine cleaning properties to the gasoline, but even those molecules are not very much affected by anything short of extremely strong magnetic fields, albeit not quite as strong as are required to affect non-polar molecules. No magnet you could fit under the hood of a car would be strong enough to have any noticeable effect on the gasoline - the only effect you could hope to see would be to have a magnet messing up the movement of the metal parts of the engine.

What are the 4 properties of magnets?
The four properties of magnets are attraction, repulsion, polarity, and magnetization. Magnets can attract or repel other magnets or magnetic materials, have a North and South pole, and can be magnetized to create their own magnetic field.
Can you twist polar bonds with magnets?
No. Polar bonds are caused buy an unequal distribution of electrons in the chemical bond, the polarity is electrostatic not magnetic so magnets have no effect.
How do electromagnets affect nearby magnets?
Electromagnets can attract or repel nearby magnets depending on their polarity. When an electromagnet is turned on, it creates a magnetic field which can influence the alignment of nearby magnets and cause them to move or align according to the field.
Do magnets repel or attract copper wire?
depends on the content of the copper wire, if its 100% usually it will
What is the hypothesis of magnets?
The hypothesis of magnets is that they contain invisible forces that attract or repel certain metals based on their polarity. This hypothesis explains the observed behavior of magnets interacting with each other and with magnetic materials.
When do 2 magnets repeal one another?
when they have the same polarity
How are magnets different other than shape and size?
polarity maybe
How magnetic trains stop?
By reversing the polarity of the magnets and there are also friction brakes.
What is the significance of ring magnet polarity in the functioning of magnetic devices?
The polarity of ring magnets is important in magnetic devices because it determines the direction of the magnetic field they produce. This polarity affects how the magnets interact with each other and with other materials, influencing the overall performance and functionality of the device.
What is the use of a magnet in a motor?
Magnets are used in motors to create motion. Magnets have two kinds of polarity, positive (north) and negative (south). When two magnets of the same polarity are facing each other, they will be attracted to each other. Conversely, if the polarity of the the two magnets are opposites than they two magnets will be repulsed. This concept of rotational motion is what is occurring in a motor.
What are the 4 properties of magnets?

Can you twist polar bonds with magnets?
No. Polar bonds are caused buy an unequal distribution of electrons in the chemical bond, the polarity is electrostatic not magnetic so magnets have no effect.
What would happen to electronics magnets etc if the earths magnetic poles changed?
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
Do waves have magnetic polarity?
No, waves do not have magnetic polarity. Waves are disturbances or vibrations that propagate through a medium or space, and they do not possess magnetic properties. Magnetic polarity is a characteristic of magnetic materials such as magnets, where they have a north and south pole.
How do electromagnets affect nearby magnets?
Electromagnets can attract or repel nearby magnets depending on their polarity. When an electromagnet is turned on, it creates a magnetic field which can influence the alignment of nearby magnets and cause them to move or align according to the field.

How do Maglev trains come to a stop?
There are magnets on the train and also on the guide rails. The polarity of the magnets can be set one way for accelerating, and the opposite way for braking. There's a flash vid at the link below.
