Unformatted text preview: Two questions: (1) How to find the force, F on the electric charge, q excreted by the field E and/or B? (2) How fields E and/or B can be created? B v q E q F + = 2 r Q k E = Gausss law for electric field Electric charges create electric field: For one not moving (v<<c) charge: Gausss law for magnetic field Magnetic charges do not exist: Amperes law Electric current creates magnetic field: (As we will see later, this law should be extended ) Faradays law (Will be discussed later ) Maxwells equations cos encl E Q A d E dA E = cos = A d B dA B B encl I l d B dl B cos = 2 7 / 1 / 1 / 10 4 A N A m T A m T = =- I in I in I out I out tot in encl B B I I = = B 7.
