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.
In physics, Gauss's law, also known as Gauss's flux theorem, is a law relating the distribution of electric charge to the resulting electric field. The surface under consideration may be a closed one enclosing a volume such as a spherical surface. The law was first formulated by Joseph-Louis Lagrange in 1773, followed by Carl Friedrich Gauss in 1813, both in the context of the attraction of ellipsoids. It is one of Maxwell's four equations, which form the basis of classical electrodynamics. Gaus
