Splain fender static charge

[JHTS]

So I was in the garage walking close past the Jeeps and the hair on my arms stood up and pulled towards the plastic fenders. Tested it on the other Jeep same thing when you wave your arm an inch or so but don’t touch the fender the hairs pull straight to the fender. Can someone explain that, just curious I’m obviously not that smart.

Static electricity
Environmental conditions

Tends to happen more in the dryer months.

Stop rubbing on your fenders

It's so you can say you had a hair-raising adventure with your Jeep, even if you never left the garage! ?

If you stopped caressing, and loving on your Wrangler so much, there wouldn't be so much electricity between you two.

I am shocked by some folks’ static responses to this thread. This guy asks a serious Jeep question, and all he gets is verbal discharge from people. If I were him, this would make my hair stand on end, and I would bolt out of here. ?

Static electricity is defined as an imbalance of electric charges in a body, especially the negative and positive charges. In other words, the discharge of an electrical pulse is known as static electricity. Physical techniques are used to create the charge imbalance. Contact between solid things is one of the most prominent sources of static electricity. The static electricity generates a force during its creation which is directly proportional to the charges of both the bodies in contact and inversely proportional to the square of the distance between them. It is known as electrostatic force and is denoted by the symbol F. Its standard unit of measurement is Newtons (N), and the dimensional formula is given by [M1L1T-2].

Static Electricity Formula
F = 1/4πε0 (q1q2 / r2)

Where,

F is the electrostatic force,
1/4πε0 = k0 is the Coulomb’s constant with a value of 9 × 109 Nm2C-2,
q1, q2 are the charge values,
r is the distance between the bodies.
Derivation
Consider a system of two bodies of charges q1 and q2 such that they are separated by a distance r. It is known that the static electricity force between these two bodies is directly proportional to the product of the charges of the bodies.

F ∝ q1q2 ⇢ (1)

Also, the force is indirectly proportional to the square of the distance between the two bodies. So we get,
F ∝ 1/r2 ⇢ (2)

From (1) and (2),

F ∝ q1q2/r2

Replacing the proportionality sign with a constant, we get,

F = k0q1q2/r2

Here, k0 is known as the Coulomb’s constant.
This derives the formula for static electricity force between two charged bodies.

You could probably make balloons stick to the fenders if you first rub the balloons on your shirt!

But, it is most likely static electricity, not some random electrical pull, or something else -- which would be ... concerning.

My fenders like to be rubbed but i wasn't just surprised that plastic held a static charge,

Are not Jeeps always a hair raising adventures?

Then my Jeeps would be unhappy.

I dont have a 4XE so I had to drive out.

Thanks for the detailed explaition. There was not contact the fenders had a static charge, both Jeeps we in the garage without being driven for over 24 hours. Just wondering why the fenders had a static charge.

I sure it would but then i would be generating the static charge, the fenders had one for some reason.

I was just giving you the formula. How the charge originated, I leave as an execise for the student.... perhaps the differential lies in you - do you wear lots of wool? ?
