Many musicians can come up with intriguing song titles, but few deliver on them with the effortless wit of Magnetic Fields front man Stephin Merritt. His indie-pop group’s latest, Love at the Bottom of the Sea, features songs with such colorful titles as “I’ve Run Away to Join...
High frequency: 2-10 cm, with big memory, is widely applied in various fields. Ultra high frequency: 1-10 m, the most sensitive, easy to be affected by humidity, dust, temperature, etc Application Festival, event, vocal concert, party, campaign, entrance, ticket,...
When metallic ferromagnetic materials are exposed to alternating magnetic fields, significant heating losses occur from eddy currents. Ferrite magnets greatly reduce such heat losses because of their high resistivity. They also absorb electromagnetic radiation of very long wavelengths. This property is ...
