Penetrating fields of spreading magnetic forces, passing rings of mysterious particles and casting a camera's eye on a strange assortment of cratered moons, the Voyager 2 spacecraft sped by distant Uranus today for the first close-up exploration of the solar system's third-largest planet. The hardy little spacecraft, two billion miles from the Earth on a voyage that began in 1977, transmitted a stream of photographs and data from which scientists in the next few days expect to make major discoveries about Uranus and its largely unknown environs. Flight controllers at the Jet Propulsion Laboratory here reported that Voyager came within 50,679 miles of the bluish-green clouds of Uranus at 12:59 P.M., Eastern standard time, slightly more than a minute behind the flight schedule that was calculated five years and nearly a billion miles ago. Closer Encounter With Moon Voyager came even closer to the moon Miranda, passing within 17,400 miles of its icy surface. The 1,800-pound Voyager raced by the sunny side of the planet at 45,000 miles an hour. The craft, operating automatically by computerized controls, was rolling steadily to keep the television cameras on target and to prevent smearing of the images. More than 200 pictures were taken over the hours of the close encounter.

What, no pineapples in January? ''My pineapples are on the way,'' Jai Rowe, the proprietor of the Paradise Market on the Upper East Side, said yesterday. He was trying to reassure his customers, who have come to expect pineapples in January. It is his secret how he managed to get pineapples in the middle of a week-old strike that has shut down the enormous Hunts Point Terminal Market in the Bronx, the main produce supplier for Mr. Rowe and the more than 1,000 greengrocers all over the city. No Tips for Competitors ''I have a good source,'' was all Mr. Rowe would say, not wanting to tip off the competition.

Prime Minister Shimon Peres of Israel said today that he had received assurances that King Hussein of Jordan had decided to move ahead toward talks with Israel, even if the Palestine Liberation Organization and Syria continued to withhold their approval. ''What I understood,'' the Prime Minister said, ''is that the King has decided to go on, no matter what sort of replies he may have in the future.'' The Israeli leader said at a news conference here that the assurances were conveyed by Richard W. Murphy, the Assistant Secretary of State for Near Eastern and South Asian Affairs, who met here this week in an intense round of talks with Mr. Peres and the Jordanian leader. King Hussein left London soon before Mr. Peres arrived on an official visit.

Representative Bobbi Fiedler, seeking to oppose Alan Cranston for his United States Senate seat this year, has been indicted by a Los Angeles County grand jury on a charge of offering a key opponent $100,000 to drop out of the Republican primary. After the charge was made public today, Mrs. Fiedler said, ''I have done nothing wrong.'' Mrs. Fiedler was indicted along with Paul Clarke, a longtime political aide and close friend, after an investigation that was begun on the basis of information provided by State Senator Ed Davis. who was considered to be her key opponent in the primary next June. Offer to Pay Off Debts Mr. Davis, a former Los Angeles police chief, told a local prosecutor that intermediary representing the Bobbi Fiedler campaign'' had contacted one of his aides offering the $100,000 to pay off Mr. Davis's campaign debts in return for his withdrawal. Mr. Davis is still in the race.

The British Minister of Trade and Industry resigned today in the furor over the Government's handling of the future of a small bankrupt helicopter company. The Minister, Leon Brittan, has been the Cabinet member closest to Prime Minister Margaret Thatcher in the controversy. He departed despite pleas from Mrs. Thatcher that he stay on. In stepping down, he became the second Cabinet casualty of the improbable Westland affair, a dispute over the company of that name that has become the object of rival rescue bids from two international consortiums.
