There are many potential causes, from psychological to very serious medical. Please see a doctor to determine what is going on.
Rubbing a balloon against clothing creates static electricity, causing the balloon to develop a negative charge. The negative charge on the balloon attracts the positive charges in the clothing, leading to an electrostatic attraction that causes the balloon to stick to the clothing.
The more the water brushes against the more the rock fades away meaning that parts of the rock is eroded ,washes away, it changes formation.
A bad belt, a bad regulator in the alternator or bad brushes in the alternator.
It has static charges. Or it may be combustible, that's why it spark and went to flame.
generally bleach is what causes white stains in clothing.
Worn brushes, bad Regulator, or Likely a bad connection or wiring.
Sparking at the brushes of a universal motor can be caused by several factors, including worn or damaged brushes, improper brush alignment, or inadequate brush pressure against the commutator. Additionally, dirt or debris on the commutator surface can lead to poor electrical contact, resulting in arcing. Excessive load on the motor or improper voltage supply may also contribute to increased sparking. Regular maintenance and inspection can help mitigate these issues.
Excessive sparking at the brushes in a DC motor can be caused by several factors, including improper alignment of the brushes, worn or damaged brushes, and uneven commutator surfaces. Additionally, excessive load on the motor, incorrect brush material, or insufficient brush pressure can also lead to increased sparking. In some cases, electrical issues such as arcing due to high voltage or a short circuit can exacerbate the problem. Addressing these issues typically involves inspecting and maintaining the brushes and commutator.
Hey Dennis==If it is an electric fan, it is probably the brushes in the motor squeeking. Not to worry.GoodluckJoe
Sharing clothing items with others that might have lice.
The function of brush is to collect current from rotating commutator and supplies the current to external stationary load. The brushes of a DC machine are placed at neutral points because the current in the rotating part drops to zero at the neutral point. If brushes are placed in location other than the neutral points, then the current may be switched off and it causes magnetic field and it may also create voltage spikes and arc at brushes.
Sometimes just sweats and irritation from the clothing.
