what is the si unit for magnetic field strength
Magnetic field The term 'magnetic field' is used for two distinct but closely related fields denoted by the symbols B and H. In the International System of Units, H is measured in units of amperes per meter and B is measured in teslas or newtons per meter per ampere. H and B differ in how they account for magnetization. In a vacuum, B and H are the same aside from units; but in a magnetized material, B/   μ 0   {\displaystyle \mu _{0}}  and H differ by the magnetization M of the material at that point in the material.
ICD-10 Work on ICD-10 began in 1983 and was completed in 1992.[1]
Ä Ä (lower case ä) is a character that represents either a letter from several extended Latin alphabets, or the letter A with an umlaut mark or diaeresis.
