A digital rectal exam (DRE) is one of the primary methods a doctor uses to check your prostate. It involves the doctor briefly inserting a finger into your rectum to feel for potential abnormalities. The abnormalities may include symptoms associated with prostate cancer, benign prostate hyperplasia (an enlarged prostate), and prostatitis (an inflamed prostate usually from infection).
Lenz Law is a way to find the direction of induced current in a conducting loop. As per Faraday's Law of electromagnetic induction, a current is induced in a conducting loop by the changing magnetic flux. This induced current itself produces a magnetic field and hence a magnetic flux.
Charles' Law, or the law of volumes, was found in 1787 by Jacques Charles. It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.
