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.
Bode's Law Kepler's Law is exact and can be derived from Newton's laws of the motion of bodies. There is another law concerning the planets but it is only approximate and cannot be derived from other laws. It is often called Bode's Law because it was popularized by Bode, but it was actually discovered by Titius.
